Clogger Posted April 15, 2021 Share Posted April 15, 2021 (edited) I have no doubt there will be optimizations , this is what the Beta is for. But I am a little concerned. in stable release I have really worked on VR settings where I have got it to a decent FPS/Graphical fidelity. The problem is with the lower FPS'es in VR there isn't much wiggle room. I do not want to reduce any in game settings and I can only afford to lose a few FPS ( I would rather lose none and see a performance increase through general behind the scenes optimizations) With the current hardware shortages, upgrading may not be possible for over another year or so (even though I think my system is still pretty good). There will be users with even less wiggle room then me and even those that managed to bag the latest hardware , having to reduce settings will be just as much of a bummer for them as even with top tier hardware i.e 3080's you are not getting any major boost in performance. I do have faith in ED but they must understand that getting the game to run well in VR is hard work and for most any performance hit may well be a show stopper.

=Panther= Posted April 15, 2021 Share Posted April 15, 2021 I’m another that had performance drop significantly. I had just recently got my frametimes in the very low teens and today’s update has pushed those into the high 30s, and mid to low FPS as well. I’m going to wipe the config, gpu driver, and retest this coming weekend. 9900k 2080ti 32gb G2 2 Twitch Channel [sIGPIC][/sIGPIC] Virtual Thunderbirds, LLC | Sponsored by Thrustmaster Z390 Aorus Xtreme, i9 9900k, G.SKILL TridentZ Series 32GB, 1080ti 11GB, Obutto R3Volution, Thrustmaster HOTAS Warthog, TPR, Cougar MFDs, FSSB R3L, JetSeat, Oculus Rift S, Buddy-Fox A-10C UFC, F/A-18C UFC, Tek Creations F-16 ICP Link to comment Share on other sites More sharing options...

Matt_j25 Posted April 15, 2021 Share Posted April 15, 2021 Depending on which preset I choose for the clouds I get either 7fps or 20 FPS. Either way it’s a bit of a loss for me also . Hopefully there will be a fix/optimisation settings we can follow to try tweak to the best we can. tried playing with my settings but not too much changes.. i7 8700k 3.2GHz, 1080Ti, 32GB ram.

apollon01 Posted April 15, 2021 Share Posted April 15, 2021 (edited) Hello, I have also experienced quite substantial performance loss in VR (9900k, 2080ti, HP Reverb G2). I managed to trace it down to a possible issue with FPS capping/locking. Example 1: motion reprojection set on auto in WMR settings for SteamVR (default.vrsettings file) - MiG 29, Instant Action Cold Start in Nevada: flips between 90 and 45 fps - so ALL OK - Su 27, Instant Action Bomber Intercept in Caucasus: fps locked at 60 - causing unplayable judders Example 2: motion reprojection forced to always on ("motionReprojectionMode": "motionvector") thus forcing DCS to run at 45 fps and letting motion reprojection do its magic - ALL OK in both scenarios above I checked also for L 39 with the same resultd as for the Su 27. Maybe worth checking this in your WMR related settings and perhaps something for ED to look at? Thanks! Edited April 15, 2021 by apollon01 Link to comment Share on other sites More sharing options...

Dave317 Posted April 15, 2021 Share Posted April 15, 2021 Poor performance here too. It seems the FPS is capped at 60 and my frame times are 40 - 50! If I alt + tab frame times go down to 20 and it's smooth again. Link to comment Share on other sites More sharing options...

Talisman_VR Posted April 15, 2021 Share Posted April 15, 2021 As a VR user this update is disappointing in the visuals department to say the least. I shan't say any more because its just too disheartening and others have already said it anyway. Back once again to flying other flight sim titles for me and I shan't be purchasing any new aircraft for DCS for the time being.

Charly314159 Posted April 15, 2021 Author Share Posted April 15, 2021 Test conditions : - Caucasus - Only one aircraft - overcast preset - settings as attached - Ryzen 4600x @ 4.8GHz, 32gb @ 3700MHz, RTX2080ti @2.1GHz, DCS on a dedicated 1to 970 evo pro nvme SSD - HP reverb G1 Everything was fluid on the last 2.5.6 versions (the first one were terrible...) using motion smoothing at 45fps. I deleted the saved game folder and did a cleanup and full repair With 2.7 I am seeing dips to low 30s with unacceptable stutter. I don't have the track as it was disabled to maximize perf. The flight was simple flying around Batumi. Looking down under over over the clouds causes a FPS dips and stutter. @BIGNEWY I have given you all requested data I hope this will be analyzed and that it's not just something to get us to wait for months like last year . dcs.log WeatherTest.miz 1 Link to comment Share on other sites More sharing options...
kelmcguir Posted April 15, 2021 Share Posted April 15, 2021 (edited) So, I had a lot of stuttering issues the first play through also, but I turned PD to 1.0 and increased Steam VR SS instead. I have a Vive Pro, so my global SS is set to 50% which is the native Vive Pro resolution, and for Per Application->DCS World SS I increased to 200%, which should be close to PD of 1.5. All of the stuttering is gone and it runs very smoothly. I have all settings maxed out as well, though I noticed that there is no difference for the clouds between low and ultra, so the clouds must be stuck on low as a bug since they look way too smooth and almost no detail like in 2D.

Csgo GE oh yeah Posted April 15, 2021 Share Posted April 15, 2021 (edited) Thanks for the tip but 'appear' and 'smoother' doesn't help me much Just by turning the clouds on (few puffs, overcast, low quality high quality not matter) will cost me 30% performance loss . (In VR) . i7@ 5,2 ghz, 32GB Ram and RTX 3090 . I would just turn them off but they're server side (and the populated servers all want to play with new clouds) so now i'm kind of out of multiplayer right now unless i drastically low every other setting which i'm not willing to do.

Charly314159 Posted April 15, 2021 Author Share Posted April 15, 2021 I was having dips to 30-35 fps with the 466.11 driver I am now pretty much locked at 45. I think 466.11 it has some strange interraction with 2.7 as it was working fine with 2.5.6. give it a try. What I don't understand so far is why some people with radeon cars have suffer are suffering as well with 2.7. Link to comment Share on other sites More sharing options...

speed-of-heat Posted April 15, 2021 Share Posted April 15, 2021 for me the increased CPU frame times, seems to have been associate with the BIOS for Rebar, that being reverted seems to gave fixed it...

Csgo GE oh yeah Posted April 15, 2021 Share Posted April 15, 2021 (edited) I haven't changed anything on my end. Just turning on clouds from "nothing" to "anything" is -30% perf . This is in VR , haven't tested in 2d yet. I'm watching 104th_bullet stream, i think GS server must be down or something because the 104th is packed but not fairing well desync wise.
