This happens with DLSS for me but not when I only use DLAA. To make it go away, force DLAA Preset K. It eats a little bit of performance but looks REALLY good! AD

You're probably right, DLSS is awesome for everything but DCS. I find that with DLAA only it's much better than MSAA though, which is pretty crappy in DCS. I don't like DLSS with it though, only DLAA by itself. With the DLSS preset K though, DLSS is still pretty impressive and takes a load off the graphics card. I just prefer it with DLAA only because it gives less artifacting. AD

Yeah, my stuttering seems to have mostly gone away. Maybe it was a monitor sync problem, I have an old monitor that is not listed as G-Sync Compatible (but it works) and is 8 years old. It's working well now, also I seem to have better luck overall with ReBAR turned off in BIOS. I still can't get my low-altitude FPS up as high as I used to with a fresh graphics driver install, though. No idea why. First time I run the sim it's awesome, next time I have problems with low FPS sometimes, but it's only when flying low near the Eiffel Tower in Normandy 2.0. AD

Ok, in my case I always have to have some kind of vertical sync enabled or I always get screen tearing even if I set my game FPS to the monitor's refresh rate (75 Hz for me.) Normal Vsync seems to cause a lot of stuttering in DCS. It could be the sim itself, or it could be a problem with the Nvidia driver causing monitor sync issues. I don't know. I just recently figured out though that if I use Fast Sync instead of Vsync and limit the FPS in-game to the monitor's max refresh (75 FPS) then I get much smoother motion without stutter and Fast Sync eliminates screen tearing, which I will always get without any kind of vertical sync enabled. Maybe I'll try limiting FPS in the NVCP instead of in DCS itself just to see what happens, but it already works well with the framerate set in DCS. AD

If I enable G-Sync compatible with no vertical sync, I get tearing. I have to use some kind of vertical sync. Fast Sync seems to work best for me, Vsync causes stuttering and BS but Fast Sync works well if I set the framerate in the Settings menu with the slider.

Yes, I can run G-Sync Compatible mode with my Omen 32" monitor. I'm now using Fast Sync instead of Vsync though, and set the framerate in the Settings menu with the slider. It just about eliminates stuttering for me. Fast Sync is needed to eliminate screen tearing, it works well. AD I'm finding that too, except I use variable refresh (Freesync enabled in monitor, G-Sync ON in NVCP.) Using normal Vsync causes stuttering for me. AD

Are you using Vsync, either in-sim or in the driver? Turn it off and use Fast Sync in the graphics driver (NVCP) instead, it eliminates screen tearing. Then set the framerate you want in-sim using the slider in the Settings menu. Greatly reduced (just about eliminated) stutters for me. DCS doesn't seem to like Vsync very much. AD

Ok, I set my pagefile to 32768 MB as per recommendations. I also found that DCS runs much smoother if I don't use Vsync either in the sim or in NVCP. Instead, I turn Vsync off in the sim and use Fast Sync in NVCP, then set the framerate I want (75 Hz for my HP Omen 32" monitor) in the sim using the slider. Runs MUCH smoother now. For whatever reason, DCS doesn't seem to like Vsync very much. Fast Sync is much better. AD

Greetings everyone, I recently tried disabling Vsync in the sim and enabled Fast Sync in NVCP. It seems to have largely eliminated my stuttering problem. Using normal Vsync either in-sim or in NVCP doesn't seem to work so well. I have to limit the framerate in-sim using the Max FPS slider (I set it to 75 FPS, which is my monitor's max) and then I use Fast Sync in NVCP. Problem mostly solved! Only thing is, I still get FPS drops when flying under the Eiffel Tower in Normandy 2.0. I had the sim going for a while without it, I could just fly under the tower and it ran a solid 75 FPS. Now it drops down to maybe 62 or so. I wish it wouldn't do that... Anyway, at least I have a handle on it. I wonder if the problem is with my monitor. I have an Nvidia graphics card and a Freesync monitor, but my monitor is about 8 years old and is not G-Sync Compatible--just normal "cheap" Freesync and not Freesync Premium or Premium Pro (my monitor is an HP Omen 32".) That might have something to do with it. I'll keep messing around with settings and see what happens. Mostly, turning off VSync seems to have helped a lot. I just use Fast Sync now because with no sync at all, I get screen tearing even when running the sim at exactly the same framerate as my monitor's refresh rate (75 Hz.) If you're having problems with this, try it yourself--it very well might be a monitor sync issue. AD

I don't have problems with crashes. Can't remember the last time DCS crashed to desktop. As for my 16 GB graphics card, I run a single 2560 x 1440 display and 16 GB seems plenty. I rarely use more than 10-12 GB at max, most games barely use 6 to 8. AD

I've tried all that, and my DCS missions don't use all 32 GB anyway. I also have 16 GB on the graphics card and usually only about 10 GB gets used, sometimes maybe ~12. Besides, I've had it running great on my current system. No idea why I sometimes get it to run perfectly after an update, only to have it start stuttering and giving lower framerates the next time I run the sim. My GAWD what a nuisance. At least they fixed the bug that gave dreadfully long mission loading times. AD

I've never been able to make arses or teakettles of the dcs.log, but here goes: Thanks for any insights! AD dcs.log

Well, I ran the sim again last night and while the loading times are still much better, the stuttering is back again and framerates are starting to drop again. Pardon my French, but <profanity> IT. It's been like this forever. It was running great, and now it's back to a stuttery mess with framerate drops. Oh well, to hell with it. AD

Yeah, I had great results flying the latest version today! I don't have the balls to try it again in case it starts stuttering again and framerates suck. I've had it happen before. Just glad it ran really nicely for the first time in months. AD EDIT: Oh yeah, loading times are a heck of a lot better now too!

Yeah, I also have Realtek sound (ALC1200) and while the sound itself always works perfectly for me, disabling solved my problems with stuttering and low framerates. Problem is, it came back again even with the sound driver disabled! So I just turned it back on. I can't sort out whether it's DCS, Windows, or crappy device drivers somewhere. This really bites. I've lost interest in DCS for the time being, maybe they'll fix it one day. AD
