Lenux Posted February 13, 2016 Share Posted February 13, 2016 How would you recommend to have the V-Sync ? On or Off ? If the monitor ( tv 4k ) has only 60 Hz, and i play with Vsync off - about 130 fps average, no tearing at all, in this case, what's the real fps ?? 60 or 130 ?

razo+r Posted February 13, 2016 Share Posted February 13, 2016 No big difference since your monitor is 60Hz, so you could turn on vsync to minimalize the stress on the gpu, because the other 70 fps are useless. The 60Hz monitor can only show 60fps Link to comment Share on other sites More sharing options...

Shez Posted February 13, 2016 Share Posted February 13, 2016 If you arent getting any tearing it diesnt matter. your tv can only show 60 fps. that's why he suggested turning vsync on. _:Windows 10 64 Bit, I7 3770 3.4Ghz, 16 Gigs Ram, GTX 960, TM Warthog, Track IR 5 w/Pro Clip:_ Link to comment Share on other sites More sharing options...

Both are real, but the measurements are made at different places. You seem to be running borderless window mode so the pipeline looks roughly like this: 1. The game and graphics card render 130 frames per second. 2. Those frames are received by the Windows renderer because you are not running exclusive fullscreen mode. 3. Windows is always v-synced no matter what your in-game setting is, so it will discard a lot of the frames it receives. The monitor then only receives one frame per v-blank, which is 60fps in your case. This is a really inefficient way to do things. I recommend you run exclusive fullscreen mode instead. Press alt+enter after you have launched DCS to make that happen. This will bypass the windows renderer, so there's nothing in between DCS, the graphics driver, graphics card and the monitor that is interfering. This also means that the v-sync option in DCS settings will work like intended. Link to comment Share on other sites More sharing options...

What's the difference between borderless and fullscreen ?! And by the way : every DCS player is using this alt+enter method after the game is launched ?

Brisse Posted February 13, 2016 Share Posted February 13, 2016 (edited) Everytime when i launch the game, it's in full screen. What's the difference between borderless and fullscreen ?! No, DCS defaults to borderless window, which is just a window without borders that covers the entire screen, but it is not true fullscreen even if it looks like it is. Borderless window forces the frames to go through the windows renderer. Exclusive fullscreen mode bypasses the Windows renderer which means the game and graphics card is in full control of how the frames are presented on your monitor. And by the way : every DCS player is using this alt+enter method after the game is launched ? Everyone that know what they are doing, yes. The benefits are less latency, properly working v-sync, zero discarded frames and thus also better power consumption, less heat, less fan noise etc...

Lenux Posted February 13, 2016 Author Share Posted February 13, 2016 Thanks a million, Brisse, didn't know that I wish i could use some mod for this alt + enter method, it should do that automatically when i launch the game I9 12900k@ 5 GHz | 32 GB DDR4 | Asus ROG Strix Z690-A Gaming Wifi d4| RTX 3090 | 6 TB SSD + 8 TB HDD | 4K Samsung Q90R 55" | VKB MK III PRO L | Virpil Throttle MONGOOST-50 | MFG Crosswind | TrackIR5 Link to comment Share on other sites More sharing options...
Brisse Posted February 13, 2016 Share Posted February 13, 2016 I wish i could use some mod for this alt + enter method, it should do that automatically when i launch the game Most game's do. Sadly, DCS stopped doing it after the 1.5 update. I hope they change it in the future, but it's really not much work to press alt+enter once every session :) Link to comment Share on other sites More sharing options...

Socket7 Posted February 13, 2016 Share Posted February 13, 2016 Your TV is doing some kind of input processing to achieve Vsync if you are not getting any tearing at all. If your TV is 60hz, then all you can see is 60FPS. All the other frames are not seen and thus "wasted". You could try Vsync and see if it works ok. If it does, your gpu will run cooler, as it will not render frames you will never see. If Vsync causes problems, you can try using a framerate limiter of some kind. Every computer and monitor is different, so you really have to experiment. Practice makes perfect. Link to comment Share on other sites More sharing options...
Lenux Posted February 14, 2016 Author Share Posted February 14, 2016 When i use Vsync, i have about 55-60 fps average, so i'm pretty hapy for now.When i play with the SU25T, for some reasons, this aircraft / missiles / is a fps killer. I dont understand why only this aircraft.

Brisse Posted February 14, 2016 Share Posted February 14, 2016 Your TV is doing some kind of input processing to achieve Vsync if you are not getting any tearing at all. No, that's not what's happening. Read the posts on page one. Basically it comes down to this: The game was running borderless window mode which forces the game to send the frames to the Windows renderer before they are sent to the monitor and Windows is always v-synced no matter what the ingame setting is. The Windows renderer is also responsible for discarding the extra frames that are rendered by the game in between every v-blank. Link to comment Share on other sites More sharing options...
Wrecking Crew Posted February 14, 2016 Share Posted February 14, 2016 I also have a two screen setup and run DCS Windowed. Alt-Enter does fill the primary monitor but the mouse won't work directly over the buttons, the alignment is off for clicking stuff.

Sporg Posted February 23, 2016 Share Posted February 23, 2016 What does full screen option do in the settings? I always thought it was to prevent running in windowed mode. At the moment it sets DCS to run in frameless window mode only. To force DCS to run true fullscreen, press Alt+Enter when in game. It usually makes it run smoother.
