Charlie-1 Posted April 25, 2020 Posted April 25, 2020 (edited) So I've had some more time to do VR testing (Rift-S) with 2.5.6 compared with 2.5.5. I'm seeing just 20FPS when in or around airfields in 2.5.6 compared to min 40FPS in 2.5.5 for some reason with exactly the same relatively high settings. (No I don't want to reduce them as all's good in 2.5.5) Strange thing is my system resources don't appear to be stretched at only 50-70% accross all and in both versions of the sim. On a positive note, out in the desert away from airfields it's running ok Test mission is 4YA Nevada capture bases, but with convoys removed. EDIT: Some strange things going on with shadows at low sun too where they appear and dissapear with head movement plus seeing some 180 degrees in wrong direction.

Devil 505 Posted April 26, 2020 Posted April 26, 2020 Anyone having issue with VR performance please read my current posts on the 2.5.6 Performance thread. It may help you guys out a lot. There are issues with the most current NVIDIA drivers and ED. I posted my findings and temp solution for the time being. It seemed to help me out. My PC specs are on the other thread as well.

Darcaem Posted April 28, 2020 Posted April 28, 2020 Glad rolling back helped you. I have no issues with 445.87. The same performance as previous versions. Forgive mi ignorance but, that version is "2.5.6.45915", isn't it? The one before the 16/04 update I use the DCS_Updater.exe update 1.2.16@release cmd command to do the rollbacks, and I will do it in order to fly this weekend if there is no fix this week. Thanks!

Fang333333 Posted April 29, 2020 Posted April 29, 2020 I fear that this performance issue is going to cost some users. I have a mate who tried DCS out on the Rift CV1 right around the time 2.5.6 was released, and he told me he tried it, but gave up after not too long due to the woeful performance. You need frames to be high enough and stable in VR or it is very uncomfortable, and just not usable. I shared with him some settings tips before and after, but I don't think he will even try it again. I am still on 2.5.5, as my DCS World was unplayable after updating to 2.5.6. I had been doing quite a lot of Nevada Aggressor missions, most recently in the Hornet, and 2.5.6 just would not allow me to use this in VR. I use DCS in VR exclusively now, and it used to be magnificent for that, but 2.5.6 has really stuffed it, to put it bluntly. I know this is still in Beta, but i just hope ED are taking this seriously, because something has gone really awry for performance to drop so severely in VR. I think they need to take a step back and figure out which move went wrong, then go back to that point and redo it. I've seen quite a few people get scared away in the last few months as well. Its probably not the best time to have a "Try All" Modules for new guys. Again I am glad DCS is doing this (I don't benefit as I own it all)...But LITERALLY the first thing I check for before I even get TEMPTED by a sim is if it will work on my system. This is exactly why I am not jumping up and down for another title that was recently released on "Alpha". Literally a sim can have Real ATC 24/7 live, ground crew animations, photoreal scenery, and graphics that melt your mind. If its a stuttery mess its not worth the time. The only reason I personally have stuck around, (and I am sure there are plenty others), is becuase I know DCS CAN work. That and I gave DCS a LOT of money. I mean a ton. Hardware, computer equipment, Rift, ALL FOR DCS. And it all sits unused now. As it has for months.

Svsmokey Posted April 29, 2020 Posted April 29, 2020 (edited) I did , after waiting 2+ months for a fix , and it broke Vaicom-again . Building a new pc , so i think i'll wait until it is done before dealing with DCS again .

Charly314159 Posted April 29, 2020 Posted April 29, 2020 You are not playing DCS at all? why don't you just do like many of us and revert to 2.5.5?? Because stable is almost impossible to use for multiplayer. 2.5.6 is tearing appart communities. Sad...
vracan Posted April 30, 2020 Posted April 30, 2020 Because stable is almost impossible to use for multiplayer. 2.5.6 is tearing appart communities. Sad... I meant beta 2.5.5, not stable 2.5.5
Eldur Posted May 3, 2020 Posted May 3, 2020 Had the chance to do some more flying in the latest version, just to notice the performance is as bad as it always has been since the second 256 version (first one did't really run at all)... absolutely no improvements yet.
RedX Posted May 3, 2020 Posted May 3, 2020 Tested yesterday, 2.5.5 -> 2.5.6 is 45fps -> 15fps on most multiplayer servers, i.e., servers with more than a couple of people and AI units. And this is with overclocked 9700k + 2080Ti. Not great, guys. I've bought 2 other VR games so far because of this, spending less and less time flying. Why not just to revert any performance-related changes since 2.5.5 and redo from scratch with performance in mind? This is about to be the route of lesser pain than trying to stitch up whatever was developed for 2.5.6 as it clearly does not work performance-wise. In general, there are complete reversals of beta branches in the history of software development with succesful results.

RealDCSpilot Posted May 3, 2020 Posted May 3, 2020 (edited) I had an issue for months that seems to be fixed with the latest hotfix driver from Nvidia. https://nvidia.custhelp.com/app/answers/detail/a_id/5022 -Fixed an issue where the shader cache was sometimes incorrectly purged on app launch While playing MP, after 1-2 hours, i had consistent framedrops that never recovered. It looked like a VRAM memory leak and the only way to solve it was to end and restart DCS. This never happened anymore since the new driver installation. Already had very long MP sessions on the same server without this issue for the last 2 days. Might be worth a look... Edit: tested a bit more and well, it doesn't solve the problem. However, those phases of extremely low FPS and stuttering are going away after a minute or two.

Shibbyland Posted May 4, 2020 Posted May 4, 2020 I'm glad this is such a common issue. I just changed from release to open beta because the MP is pretty much non-existent on release version. With the exact same systems settings, open beta is just unplayable in terms of performance. I'm getting a number of other minor bugs which do affect my enjoyment somewhat but that's to be expected with open beta. The difference in performance between release and open beta is huge. Stupidly, I uninstalled stable version before testing open beta...and now I'll have to redownload stable all over again. Multiplayer is not worth it if the game is unplayable performance wise. Please don't bring this over to release version.
doraymon Posted May 7, 2020 Posted May 7, 2020 I just pulled the trigger on a new PC exclusively for DCS in VR, and now I read about these issues. Sorry for the silly question., but what ballpark FPS shall I expect with HP Reverb and the following PC configuration: Core i5-9600KF, 32GB DDR4, RTX 2070 Super, 500GB SSD Samsung 970 EVO Plus Thanks for your help.

speed-of-heat Posted May 7, 2020 Posted May 7, 2020 a lot depends on your settings and cooling but i would expect you can get to a pretty constant 45 FPS, if you are on 2.5.6. you might get some drops, turn mirrors off and you will be good SYSTEM SPECS: Hardware AMD 9800X3D, 64Gb RAM, 4090 FE, Virpil T50CM3 Throttle, WinWIng Orion 2 & F-16EX + MFG Crosswinds V2, Varjo Aero SOFTWARE: Microsoft Windows 11, VoiceAttack & VAICOM PRO YOUTUBE CHANNEL: @speed-of-heat

speed-of-heat Posted May 7, 2020 Posted May 7, 2020 (edited) on a reverb the maximum FPS is 90Hz, however in practice you will not sustain that which introduces "juddering" in your view and likely nausea, however there is a technology in WMR/SteamVR which essentially enables the GPU to guess the next frame so it functionally only has to render every other one that gives you 45 FPS usually stable, this is called Motion Reprojection in SteamVR and ASW in Oculus but they are largely the same, suggest google... If you are coming from the 2d world this will fill you with horror, it really shouldn't as you can get perfectly smooth and acceptable play at this "45" FPS, which looks like 90 to the eye. In context on my box which is similar practical specs to yours, i get well over 144 FPS on my settings for VR in 2d, where i get a stable 45 and i am quite happy. if you are wondering about why ... well thats because the game is rendering 2160 x 2160 x 2 as well as doing the whole making the world look like t3 d calculations, and to be fair it doesnt do it very well today... that said even if you could halve it the practical maximum on your reverb is 90 because thats the refresh rate for the device. some users have experimented with forcing the reverb into 60hz mode and that works and i can usually get a pretty consistent 60FPS in that mode but i find the shimmering off putting...

panph90 Posted May 12, 2020 Posted May 12, 2020 I noticed the worse performance are in Persian Gulf with F14... With my hardware i would run at 40 in every condition... In PG with F14, 20fps on stennis, 25 in high altitude flight and 10-12 while bombing some trucks al low altitude... Literally unplayable! Ah mirror off.. with mirror is even worse. The strange thing is that i got that fps in EVERY graphics settings. I usually run in High with low terrain and medium vis range, 2x MSAA. I tried to lowest to highest settings, i have exactly the same performance... i think i'll revert to 2.5.5... ___________________________________ DCS 2.5.6 Open Beta - F-18C, F-14B, F-16C, Av-8b, A-10C, Uh-1h, SA-342, Mi-8MTV2, KA-50 Modules Persian Gulf Map, Nevada Training Map ALIENWARE AREA-51 INTEL Intel I9-9940X - Nvidia 2080Ti 11Gb - 32GB RAM - 4TB SSD Oculus Rift S - FULL VIRPIL SETUP: T50CM2 throttle, T50cm2 Base and Grip, ACE2 Rudder

ED should have never released 2.5.6 before they could at least evaluated it internally better.
