Art-J Posted April 15, 2021 Share Posted April 15, 2021 Following BN's advice, updated NV drivers to latest ones today, same with Reshade (I only use it for SMAA and bigger fps display), also, apart from obvious fxo and metashaders purging I dumped the old options.lua and had redone all settings. Disabled mods, did repair. All that gave me an increase of... 1 (one) fps on average, 2 in some glorious situations :D. That being said, tried what was said in the other thread and I can confirm something FUBAR's going on with how 2.7 works with V-Sync and Full-Screen option (as has often been the case in post 2.2-era... sigh...). Testing again in TF-51 Batumi hot-start instant mission, Full Screen option always turned ON, and looking to the right towards hangars and trees immediately after spawning: a) In-game V-Sync ON, driver V-Sync ON or adaptive - fps starts at 60 but quickly plummets down through 40s into 30s - that's the big performance drop I reported yesterday. One could say two V-Syncs shouldn't be needed, but It didn't work that way in 2.5.6; b) In-game V-Sync OFF, driver V-Sync ON or adaptive - fps stays at 60 most of the time (yay, I guess), drops occasionally to high 50s with screen tearing - well, that's a big improvement at last. I could even enable some scenery mods again, though I'll still have to turn down some 2.5.6-proven gfx settings to avoid getting below minimum 60. Means the performance drop is still there, though not as bad as in a) case; c) In-game V-Sync ON, driver V-Sync OFF - fps all over the place, from 50s to 80s, screen tearing - clearly the game doesn't launch in Full Screen mode but borderless windowed. Alt-Entering back and forth makes the game even more confused, with V-Sync activating or not without a clear rule... I'll have to settle on b) and try to tweak more from there. 2 i7 9700K @ stock speed, single GTX1070, 32 gigs of RAM, TH Warthog, MFG Crosswind, Win10.

But i understand that its more easy to optimize for good/new hardware. Also not so much time needed as it would be if optimize too for older stuff. Enough people have complained, so its clear to me that there was not enough optimization in process before update. Again not pointing all fingers to client side pls. I think nobody complained here before the update i read more like people was happy with the performance on there settings before. And guys, dont tell people again roll back the update or your GPU is the problem what i read mutiple times here. That is not the point and we start spinning in circles... AGAIN before it was just fine. Let we ED work on it to bring performance back, BUT DO IT pls and not only look on client side like lower settings.. thx 4 Link to comment Share on other sites More sharing options...

I've installed 466.11 today and lost only 2 frames compared to an old one (cannot remember version number, but it was not 461.72). I will try 461.72. Not too optimistic though, they usually tweak them for newest hardware. For old hardware it might be the best to keep old drivers. Not older hardware, unless a 3090 is "old" Well, here is my saga... And it frankly doesn't make sense. Get DCS yesterday and Test (was on "older" driver, not sure which one, maybe 461.72 or the one after) Frames kinda suck relative to previous offline. I.e. the aforementioned drop from 10ms to 15ms. Update driver to see if its the issue. Nope, new driver is the same or worse. Test online, terrible frame rates, but thats like CPU frame related. Check logfile, see a bunch of DX11 errors relating to shaders and clouds Today, did repair, it found 600 files wrong (maybe skinpacks? IDK) Retest offline, nope still sucky 15ms frametimes in tf51/tiblisi Check logfile, errors still there. Start turning off settings, steam had been bumped up a bit from 2100x to 2700x, so turned that back down Nope frametimes still suck... Turn off the dynamic cockpit lighting... Hey got 1-2ms back... Check clouds... No change from hi-low... Out of desperation revert to oold driver... Boom, frametimes back to 10ms... Test online, well its certainly better than it was, but CPU frametime is still a bit high. 4 minutes ago, yogipol said: I do have same experience with 2.7 so far. 9700k with 6900xt cannot maintain steady 45fps in VR (G2) in my case.

This happened everywhere I went in the Caucasus map, both single and multiplayer. I haven’t spent any time in the other maps since the upgrade.

Canada_Moose Posted April 16, 2021 Share Posted April 16, 2021 For what it’s worth, after the patch for 2.7 installed, I went ahead and ran a repair straight away which found a fairly large number of issues.

Maksim Savelev Posted April 16, 2021 Share Posted April 16, 2021 (edited) Using a rig of AMD5900x and RTX3090 I found out that in VR DCS 2.7 is utilizing a lot of CPU(comparing to 2.5.6)and a lot of stutters and frame drops just disappeared, and it’s a good sign. And as developers say the performance is really smooth even over dense cities, BUT when you’re looking just straight ahead! When you’re trying to look on aside it becomes a terrible mess, FPS drops below 45 in VR causing unplayable experience. Of course it was a difficult test for 2.5.6 version as well , but with the same graphics settings I could get away with 45fps in most of scenarios. The only problem map was the Channel. In 2.7 almost every village or forest in every map can drop you below 45 during low pass when you’re looking over the wing. Doesn’t it mean that something is different now performance wise? Rig is same, setting are the same, I’ve done the “magic” with the Saved Games folder. Any other options to get happy low passes back:)? Forgot to mention, that for me CPUms became better in 2.7 along with better CPU utilization, Edited April 16, 2021 by Maksim Savelev 1 Link to comment Share on other sites More sharing options...
SCPanda Posted April 16, 2021 Share Posted April 16, 2021 21 hours ago, zerO_crash said: Haha, I had to repair the install, and indeed it improved my framerate on Caucasus as well. The other maps were great from the start, but it was Caucasus that could cause small jitters, that is mostly gone now. I guess the little that remains, has to do with the optimisation of the map I also got frame drops on Caucasus, and it's pretty weird because I get lower frames in the air than on the airport. I say lower frames I mean sometimes the frames will drop for some reason and I was not near or looking a crowded area. Also the overall frames on Caucasus is much lower than 2.5.6. I have already tried deleting the saved games folder for DCS and didn't notice any improvement. I will try to repair and install (I'm on steam so verify game files I guess). Hope it works. Also I just don't get why some people are reporting better frames in 2.7, all I experience is lower fps (not much but definitely about 15-20 fps loss) than 2.5.6, before the update game is super smooth on all maps, but now the game performance is not as good as before. Also, I don't think the new cloud is causing the performance issue, when I look at the clouds my FPS is ok and equal to 2.5.6, but looking at the terrain, worse FPS than previous open beta.

Althar93 Posted April 16, 2021 Share Posted April 16, 2021 i7-4790 RTX2060 6GB with 16GB RAM here I would say that with identical settings, I am getting more or less the same framerate in 2.7 as I did previously, which is to say around 40-60FPS between the worst case scenario (multiplayer, on the ground in crowded areas) and best case scenario (single player, in the air). I wouldn't mind further optimisations as a higher framerate is always nice but overall the game / update runs pretty well given all of the visual additions & clouds.

Gretsch_Man Posted April 16, 2021 Share Posted April 16, 2021 (edited) I'm also having performance issues with 2.7. in VR (Rift-S). What helped me quite a bit was switching from Steam VR to Opencomposite and Oculus Tool Tray. OTT Default ASW Mode set to 18Hz. That may seems to be a very low frequency setting, but fps appears to be MUCH smoother now. Any Rift/Rift-S may want to give it a shot.
