With your specs I dont think you need help from frame interpolation to get 60fps! What model sony set do you have?

4K UHD TV w/ Frame Interpolation - 60FPS Results for 30FPS Settings (Sort of) I am experimenting (so far with success) in generating a 4K (3840x2160x60hz) 60FPS smooth playing experience while using settings and CPU/GPU that can only produce 30FPS in game output. The cost is input lag / latency, but so far I'm very happy with the results and thought I'd share. Why am I doing this? I want the visual fidelity of 4K. I want the smoothness of 60fps - especially for TrackIR. I want to keep my existing hardware: -I7 @4.2Ghz -970 GTX Stock -TrackIR - 8GB Ram - SSD -Samsung 40" 640D UHD Display w/ AutoMotion (frame interpolation) There are two key enablers: 1) A high quality UHD display with frame interpolation / smoothing connected via a 60hz display port or HDMI 2.0 connection 2) NVIDIA card with the Adaptive Vsync (Half refresh rate) option. Let me be clear. The trade off of this is a latency increase. The amount depends on the specific UHD display and how it processes the image. The amount of latency that is acceptable is purely subjective. For me I am OK with latency in flight sims as it is less of a 'twitch' experience and more of a 'flowing' gameplay experience. Fluidity and visual fidelity is more important to me than reflex and response rate. That said I personally would not do this for ARMA or other First Person shooters where reaction / response time are more important. A short explanation of frame interpolation: Frame interpolation was designed for video / movie playback to smooth out the judder that occurs during panning scenes in movies and video. It processes the 24fps (film) or 30fps (video/tv) and interpolates frames to 60fps (or even 120fps) to produce smooth(er) pans. Obviously video and film playback are not games. They are at fixed frame rates, so - for interpolation to work it REQUIRES a consistent input FPS. For this experiment to work DCS needs to be running like it's a 'movie' at a fixed FPS. I chose 30FPS for two simple reasons 1) I could run DCS with very high settings and achieve 30FPS in all scenarios 2) 30FPS was the only frame rate I could 'lock' the game at.. more below on this... How I did it: Step 1- Setup the game for ROCK SOLID MINIMUM OF 30FPS IN ALL SCENARIOS AT THE NATIVE RESOLUTION OF 3840X2160X60hz This is super important. This will ensure the video signal the UHD display sees will never be below 30FPS. With my hardware to achieve a min of 30FPS (online and offline) I have almost everything turned up pretty to high or max with the exception of: - MSAA OFF (frame killer at these resolutions when zooming in). Use FXAA in NVIDIA Control Panel - Vsync OFF (see below) - View distance High - Tree's 20K - No clutter / bushes (they bother me) - Shadows High - Flat terrain shadows Step 2 - Ensure frames never go over 30FPS by turning on Adaptive VSync (Half Refresh Rate) in the NVIDIA control panel . I am running native 3840x2160x60hz, so this feature locks GPU output to 30hz (or 30FPS). I was not aware that NVIDIA offered this feature until I fell upon it accidentally. I'm sure this isn't the purpose of the feature, and I don't know if AMD cards have something similar but it's the critical enabler to make frame interpolaton work as it caps at a lower frame rate than native monitor refresh rate (and dynamic GPU capability). If you did the above two steps correctly when you enter DCS (and watch your frame rate counter) you should see 30FPS with very little fluctuation. Fly over trees, city areas, low fly vegas etc etc... should stay at 30FPS. NOTE - NVIDIA Adaptive Vsync needs to be in full screen mode. Make sure you press alt-enter after you start DCS. FPS counter - should be 30FPS. Step 3 - Enable your UHD displays frame interpolation mode. Every company calls it something different. I have a Samsung UHD display and they call it "Auto-Motion". It has 10 levels of 'smoothing' plus a couple of presets. I just use the default 'smooth' preset. Your display should now be processing the solid 30FPS "DCS Movie" signal into a 60FPS output on the monitor. You will notice increased latency (how much depending on the display and its processing methods). The quality of the interpolation is also going to vary display to display. I can only comment to what I am using: - Samsung 40" 640D (also the same as a 6400D and 6500D). I chose this monitor based on its response time, latency performance, almost zero ghosting, and price. I was not planning on using interpolation as described above but - it seems to be working very well likely enabled by the core properties of the display. I paid $399 for a factory refurbished unit. Here's a link to review other UHD TV's as gaming monitors that I found very helpful. You'll find no mention of interpolation used like this and the latency / response times are representative of modes NOT using any image processing in the display like interpolation. However, it may be a fair assumption that a very fast, low latency display in it's GAMING mode may realize benefits in its processing modes (maybe...). I can say that this Samsung display has the best interpolation performance I have seen in a display relative to ghosting and blur at a latency level that is acceptable for flight simulation (for me). http://www.rtings.com/tv/reviews/by-usage/pc-monitor/best Results I could not be happier. It isn't without it's hiccups, and the latency is noticeable. The biggest latency issue I had was with TrackIR. I had to reduce the TrackIR smoothing as this was introducing even more latency. I'm still playing with it but so far I'm super happy. 30FPS rendering allows me to have mega detail, view distance and visuals at 4K, while the half refresh rate / interpolation makes everything super super smooth. For now this is my default playing setup for DCS. Thought I'd share.

mmm... another revenue generation based 'update'. Great.

I have an issue in 2.0 and 1.5.3 where I get big drops in FPS only when zoomed in on a city center. Even at very low altitudes when in normal zoom I get 60FPS locked (frame capped) no matter what. I can pan with trackIR rapidly, down the stip in vegas or buzzing a city in the Caucauses at very low altitude I get 60fps. If I zoom in on a city area however that changes... frames will drop 20-30% (even when sim is paused). Just for kicks I dropped to LOW preset and I get the same frame drop only when zooming in on a city / populated area. i7 4.2Ghz Nvidia 970 60FPS locked performance using custom settings (not a preset), but it's probably between Medium and High. I can't for the life of me find the 'setting' that is controlling zoomed city performance... looking for suggestions.

Anyone having siginificant frame drops only when zooming in on Las Vegas (or city areas)? Get 60FPS locked at normal zoom buzzing vegas at very low altitude. As zoom increases (even with sim paused) FPS starts to tank. Any suggestions? Note - even on lowest preset still get FPS drops below 60 when zooming in to max zoom on a building filled landscape. Running I7 4.2Ghz w/970.

Running on max settings my DCS does not consume even up to 8gb system memory. I monitor memory utilization while playing on a second screen. why do you say 16gb is required? I am also running 4k. gpu memory is maxed but system ram never gets maxed out for me.

this is great info. Do you know if there is a similar config file for A-10A ? I looked but could not locate. I'd like to modify overall text size as well as X and Y position of the heading tape, Navigation block and the airspeed and altitude boxes in the A-10A and maybe F-15

Thinking about this more three things would be needed. 1) Like A-10C add option to reduce text size for A-10A. The font currently on A-10A is very large for 4K. 2) Move position of Airspeed,altitude, and navigation block inboard about 10-20%. 3) move heading tape and Navigation block up 10-20% No need to move or resize any targeting cues. The HUD eye box can stay the same so no impact to targeting cues or overall calibration. etc... Can these be done now in any lua files for A-10A?

I updated to latest version and can connect perfectly. Update!

yes please!!

Issue common with A-10C When view point set to proper virtual pilot eye point HUD projected image extends beyond borders of HUD glass / frame drastically. HUD projected image is contained within the HUD frame when pilot eye point is placed very far ahead of seat head rest position. The issue with this is that in order to achieve proper FOV while flying eye point at the virtual pilot eye point is necessary and at this eye point no useful HUD info is seen (knts, altitude...). In order to see useful HUD info eye point must translate forward to almost ahead of the stick and much of the FOV outside of the HUD frame is lost. This is a big problem with 4K displays as reading the HUD text at a viewpoint of the actual virtual pilot eye point is very feasible given the increased display resolution.

Need a way to scale down the overall rectangle of the projected HUD image onto the HUD glass. With a 4K display, putting the eye point at the correct spot (same as virtual pilot eye point near seat back - not with chin on the dash like default condition) the HUD projected image is far too large and projects beyond the HUD frame. This is a problem with A-10A and A-10C. There is a font scaling option but it does not alter the size of overall projected foot-print of the HUD image. http://forums.eagle.ru/showthread.php?p=2713932#post2713932

+1+1+1... same thing on A-10A. I just went to 4K and this is a big problem now. If I position eye point at the actual eye point of the virtual pilot using CTRL -ALT-/ OR * I get a perfect FOV and positional awareness. But the HUD image is blown up beyond the borders of the HUD frame I tried the text scaling mod but it just shrinks the text of each element keeping its positon, it does not actually make the overall HUD projected image / area any smaller. Can someone help (PeterP?). This is a must have for 4K.

Agree. I picked up a 40" Samsung 640D and it is FANTASTIC with pretty good response time given an IPS panel. I'm running a single 970 with an I7 at 4.2ghz. MSAA off. Still messing with other settings to get to a solid 60fps online and in Nevada low level, but 40fps is pretty nice. Note - one benefit of getting a high quality UHD set with good response time is, for certain applications, the option to use frame creation / smoothing to reduce panning judder etc... The price you pay is increased latency, but in a flight sim (vs first person shooter) additional latency is not so important for me and given this panel has low latency to start the change is not noticeable. Anyone else running a single 970 at 4K? Could you share your settings? I know there is an issue with 970's running at max memory (don't actually have 4GB of usable memory) causing skips but I'm not sure how to manage in DCS. Would like to see other folks settings. Thanks

Any hints on what Skynet has coming for us??

I agree. I am seeing the same good performance with a single 970. I am using a Samsung 40" UHD TV and it is really nice. Can't recommend it enough. - can still run 1080p on a 4K and it looks as good as native 1080p panel - can use gaming mode for good response time (eg twitch gaming in First Person Shooters) - can use 120hz frame creation (smoothing) in flight sims for super smooth panning (judder / jitter reduction during panning with trackIR etc..) About the only downside is the size of text (chat, radio chatter, ATC menu)... it's tiny and hard to read.

I have a single 970 and its great ("decent enough"). I can't recommend Samsung UHD sets enough for 4K PC gaming....

Thanks. This would be good to include in setup instructions!

Great to hear! Can't wait to sign on tomorrow... maybe with a new 4k monitor!!

Can you please explain how to do this? I am having the same issue and would like to change the spoken word association to each profile but I don't know where to set that up. EDIT Able to figure it out inside the individual 'EDIT PROFILE' within VOICEATTACK. Used nouns vs fighter codes and it works great. F-15C = "EAGLE" A-10A = "HOG" A-10C = "BOAR" SU-25T = "TOAD" SU-27 = "FLANKER" F-86 = "SABRE" P-51 = "MUSTANG" It's a bit of a pain to copy profile switch commands to each of the plane profiles but the Copy-to command makes it faster. Should consider for next VAICOM release to maybe include noun based profile switch designations in addition to the normal F-XX SU-XX P-XX fighter codes.

Using the time to learn another plane..... SU-27 is interesting indeed! patience is a virtue I guess!

If only it wasn't private!!!! [ame] [/ame]

Any changes with latest update?

Thanks allot. Can't wait to get back on the map and see what Skynet has for us.

Yikes me too! Looking to play on my favorite server. Hopefully it comes back soon!
