No, I'm not using any add-ons or mods at all. I just use the keyboard commands for all the radio orders. AD

Yeah, the external model is old but it's also very good. The Su-25T is a free module and it's a pretty darn good one! Enjoy it for what it is. AD

Greetings everyone, I'm flying a 'furball' mission over Normandy 2.0 a lot, and always notice that issuing radio calls such as Cover Me or Engage Bandits will cause my FPS to drop noticeably for a very short time. Otherwise, performance is excellent. Anyone have any ideas? AD

HR, I find that DLAA is just a heck of a lot better than MSAA. DLAA has some slight ghosting but it's not that bad. MSAA has "crawlies" that drive me bananas. There is no AMD equivalent (yet) because DLAA and DLSS as well require specialized hardware. They are not generic algorithms that can run on any graphics card like MSAA. So, Nvidia it is. Performance-wise though, the new AMD cards are great. Make sure you enable MFAA (Multi-Frame Antialiasing) in the graphics driver if it's available because it does a much nicer job with MSAA enabled (they work together, MFAA by itself doesn't do anything.) AD

Leave Low-Latency Mode Turned OFF for flight sims because allowing pre-rendered frames gives better FPS and better frame pacing (minimizes stutters for a better impression of flight.) Turn it on for twitchy FPS games. AD

Emperor, Flashing graphics were fixed in DCS itself a while back. Remove all graphics card overclocks and run the sim. Down-clock your GPU and even graphics memory and try it. This was a common problem a while back but 4000 series cards are much better. Try it anyway. A 400 card should run well at 2500-2600 MHz or so. AD

Thanks for the help everyone, I tried increasing buffer sizes as per Mustang's post about terrainoptions41.lua. It made no difference for me. I'm using about 10.5GB of graphics memory out of my 16GB and still get glitching of ground objects. AD

No kidding, today's PC hardware is killer and it doesn't even have to be top-of-the-line stuff. Ought to be able to make use of it more. AD

Question as per thread title. It only seems to affect NTTR, the other maps work fine. Deleted fxo/metashaders, latest graphics driver, lots of VRAM available (using only about 6-7 GB out of the 15.2 GB budgeted on my 16 GB card) and DCS is installed on a fast NVMe 4.0 drive with 64 GB pagefile. Framerates in all maps are outstanding, loading times are very good. NTTR is just blurry and takes quite a long time to load the ground textures. Building/trees/etc. load just fine. Any ideas? System spex in sig. AD

It's just a simulator. Suck it and see! The Hornet has a low wing loading for a modern fighter jet and has big ass flaps. Try it out yourself! AD

Greetings everyone, I tried cranking the Extreme disancfactor up to 3.0 and even 5.0. It certainly draws further out and uses up more VRAM (~10GB instead of only the usual 6 to 8 GB) but it causes lots of glitching of local buildings in the London area of Normandy 2.0. It even causes entire city blocks of building to fail to render! It's weird because the framerates are still awesome, but buildings flicker on and off. My guess is that it's an inherent limitation of DirectX 11 and improving it greatly will require the new implementation of the sim in Vulkan or DX12. The best I could do was increase the Extreme distance factor from 1.5 to 2.0, using 3.0 or higher causes visual glitching. Thanks! AD

Awesome, thanks so much! AD

No kidding, the new graphics cards are awesome and I just got one with 16GB of VRAM. I paid for 16GB of VRAM and I wanna use 16GB of VRAM I really, really wanna know how to crank up the draw distances! The better cards these days can handle it. Somebody help! AD

I know people have tried this in the past but I'm talking about the latest-and-greatest Multithread version of DCS which now offers great performance! My machine is up to the task so can anyone help? Can I edit any config files to increase draw distances for trees, buildings, shadows etc.? If so, how to I do it? I wanna use all 16GB of my graphics memory and load up my nice new GPU AD

Same here, I have a capable system but this drove me bananas for a while. Turning off Civil Traffic not only removes the periodic stutter (more like the simulation cyclically speeding up and slowing down) but also gives much better framerates overall. Hope ED fixes this one day because lots of heavy ground traffic really makes a city feel like a city--headlights and taillights everywhere. Built-up areas NEED it to be convincing, especially at night where it looks awesome. AD

Can definitely confirm! Civil Traffic causes my system to have a weird "metronomic stutter" over heavily built-up areas like London and Paris in Normandy 2.0 but setting it to Off completely removes it. Everything's now liquidy buttery smooth even at ALL MAX graphics settings and exudes concentrated awesomeness! I'll miss the cars and crap but I guess I can turn them on individually in the Mission Editor for other maps where it isn't a problem. It mostly seems to affect those two parts of Normandy 2.0 really badly. Oh man am I glad I found this thread. I was ready to buy a new processor I can't afford Peace and happy warfare AD

I have a 5800X (non-X3D) processor which has 8 cores and 16 threads. I find DCS performs much better with SMT enabled for all 16 threads, when I turn off SMT I get very heavy stuttering over Paris and London in the Normandy 2.0 map. Enabling SMT allows DCS MT to run pretty decently, but when I fly low over Paris or London I still get noticeable frame pacing variations making it look like the plane is speeding up and slowing down. At least it doesn't stutter heavily like with SMT turned off. Try it yourself and see! DCS is brutally demanding with all the eye candy cranked up so I think you're better off with SMT enabled. It generally makes everything run better including DCS. AD EDIT: I eliminated the stuttering and annoying frametime variations simply by turning off Civil Traffic! Runs like an absolute charm now. I haven't tried it with SMT turned off yet but see no need to.

I used to have DCS on a PCIe 3.0 NVMe drive, ran out of space, bought a new 2TB PCIe 4.0 drive (twice as fast.) It doesn't really make any difference in loading times. The new drive benchmarks with WILD performance but it's no big deal in actual use so I wouldn't get worked up about it. Your motherboard only supports PCIe 3.0 anyway, but you can install a 4.0 drive if you wish and it will run at 3.0 speeds. It's no big deal, go ahead and get a new drive. It will not drastically improve loading times over your SATA SSD, but it should be a bit faster. It's for video games. Just buy what's on sale. That's the real answer. AD

Your computer is almost identical to mine (see my sig) and should run DCS like a breeze, no problem at all especially on a single screen. Check your system performance with something like MSI Afterburner and Task Manager, see if it appears to be bottlenecking anywhere. You should have no problems running DCS Multithreaded and have great performance. Oh yeah, check first to make sure you haven't set a framerate limit in your graphics driver or something like RTSS! Just use Vsync. Also, use this link to make sure your monitor isn't skipping frames: https://www.testufo.com/frameskipping#horiz=15&vert=8 Does your machine run everything else well but just not DCS?

I think that DLSS is awesome! Just not for flight sims. In anything else, it makes my 3070 perform like a 3090 Ti In DCS though the little "crumbly and wiggly" effects are noticeable even on the Quality setting. In all fairness, the atmosphere itself probably does a heck of a lot of that kind of thing so it's not at all unrealistic. Just annoying in a flight sim. Unfortunately it seems that DLSS causes some motion blurring and weird artifacts on cockpit displays and mirrors. So, it's implementation in DCS is not perfected yet. Performance in the Multithreaded version of the sim is so good now that by the time the Vulkan API version comes around, I doubt it'll be necessary for many people to use DLSS at all unless you're on an uber-tight budget and need to use your old ass RTX 2060. AD TECHNOLOGY IS A SIN!!! ELECTRICITY IS A SIN!!! No wait, that was a different game! AD

Jackd, I'm pretty sure the only thing Game Mode does is run everything else in the background at low framerates to minimize the CPU load. If you have a modern PC with, say, 8 or more CPU cores (or 6 really fast ones such as a Ryzen 5 7600X) then it probably makes no difference either in DCS or anything else. You can try turning it on or off as you wish, I've done so but never really noticed any difference. AD

Tell that to NVCP AD

My holy huckin' GAWD, you people and your beast PCs. You have no excuse for stutters. Now stop playing games on it and use it to design a real fighter jet Anyway, it has been well-known for a long time that the shadow system in DCS isn't all that great, is pretty confusing at times, and causes stuttering. It doesn't cause stuttering for me, but I do find that I have to set ground shadows to Flat instead of Default to avoid heavy framerate drops at low altitudes over built-up areas. Maybe they'll re-write that part of the sim sometime in the years to come, but I wouldn't hold my breath. AD

Greetings, I just bought a new Aorus Elite B550 motherboard with a new Ryzen 7 5800X processor (8C, 16T) and 32GB of DDR4 3600 MHz RAM to replace my aging i5-6600K Z170-based system. I reused my existing RTX 3070 card which I've had for almost a year. Man oh man does it run just brilliantly! I run at my monitor's 75 Hz refresh rate with G-Sync and VSync on, and it's 100% stutter-free and I don't even need DLSS! Just MSAA 4x and that's it. I'm running at all MAX settings except for View Distance which is set to Ultra instead of Extreme. I get butter-smooth 75 FPS all the time now, and butter-smooth 60-65ish FPS with mirrors on at 1024 full refresh rate! I don't even have to run my new CPU at full speed, 4.0 GHz on all 8 cores at 1.0V is fine and it's a breeze to cool with my existing old cooler (Hyper 212 EVO.) It looks like DCS 2.9 is living up to the hype, it definitely runs like it should now. Bring on the Vulkan API version now Awesomeness! AD
