Hey everyone, I'm planning to upgrade my GPU from 8 GB 3060Ti to 24 GB 7900XTX only to get better performance flying in DCS in my Quest 3 (steady 90 FPS and excellent quality) I did an extensive search, and I found mixed results! Apparently, in some cases, having an AMD CPU helps the AMD GPU boost their performance and most of the negative reviews come from Intel CPUs, but couldn't find any tests for DCS to compare My specs are as below: CPU: AMD Ryzen 7 7700X 5.4GHz 40MB (8-Core) Memory: 64 GB RAM (2x 32GB 6000MHz DDR5) SSD: 2x 2TB Kingstone KC3000 M.2 NVMe 7000MB/s -
Effect that makes it unplayable is both eyes image lagging-shifting while rotating or moving head. This sometimes happens without FPS drop on the FSP counter. Next day I tested it and it looks like there is a large frame drop when simply moving head even in the start screen/menus. Image lags in stutter-like manner.(not sure how to describe it correctly) This is probably not classical stuttering,I think, image does not pause, instead image doubles and goes off center very fast. Well, shifted image might lag, I don't know for sure. my system: Mobo: MSI B450 tomahawk max CPU : Ryzen 3600 RAM : 32GB ram SSD : 1TB samsung(for DCS) GPU : Asrock RX6950xt (previous GPU GTX 1080ti) PSU : 850W gold plus VR : HP Reverb G2 things I already tried with no success. -dcs cleanup -dcs repair -removed fxo and metashaders -Low DCS settigs and lowest pixel density -reprojection on, locks frames but very low FPS(in ST repojection seems to not work at all) -reprojection off-effect extremly pronounced but higher FPS 60-90 in DCS initial screen. -Set headset frequency to 60Hz -various Open XR tool settings(prefer framerate over latency on/off, latest preview openXR on/off) -tried xr companion app-doesnt work(or crash MT),(in ST it doesnt show menu-it doesnt work) -various "solutions" on DCS forum regarding stuttering in VR. -AMD SAM on and off(resisable BAR/SmartAccesMemory) -various AMD Adrenalin software settings, from default to all off or lowest. things to notice: -I had no issues like this on Nvidia GTX1080ti, I had really good gains in performance in MT. (only xr companion app would not work or it would crash DCS MT so I disabled it.) -Reprojeciton worked on Nvidia ST and MT -This does not happen in other games I tried(MFS2020, Spaceengine) -I Instaled new gpu using DDU(meaning previous drivers are thoroughly removed) -I instaled new chipset drivers I did not update bios jet. Video was very hard to record, it was recorded at 60FPS(smartphone camera). dcs MT VR AMD problem.mp4 -
The following post includes both issue and the solution I have found after testing and troubleshooting for the sake of reproduction, testing and fixing (if possible). Hey everyone, For weeks I have been plagued by FPS issues during multiplayer sessions on well known Servers such as BlueFlag, the Growling Sidewinder as well as Graywolfs Grayflag Server, pretty much making the game unplayable near ground, in cockpit or as a whole. These issues are severe, since the game drops from [my] regular 80-110fps (depending on terrain and surroundings) to 12-30fps. I was extensively trying to find the cause of this issue - especially since, mostly playing online and PvP (DCS competitive too), it meant that there was not much to do for me in game with frames always being this low. Knowing that AMD never had the best or most stable GPU drivers, I was almost certain that it was related to my drivers - especially since that issue popped up (again) after updating to the newest one a few weeks back. I tried out different DCS Graphics settings (I think i might have tested out every possible combination by now), clean installing different GPU drivers (with DDU ensuring a true clean install), tried testing it with and without community mods, and so on and so forth. The most annoying part of this issue is that it felt unreproducible, unpredictable and persistent until I restart my game, only to sometimes realize that the issue comes back after a couple of seconds or minutes after slotting into a plane. The following findings have been learned with a vanilla DCS install (No Mods, Full Repair etc.). Trying out different recent AMD drivers did not seem to improve the situation, until I decided to turn off my Radeon ReLive feature. This feature records the last x seconds for you to save on pressing a Hotkey - an instant replay feature also known as NVIDIA Shadow Play on NVIDIA GPUs. Here's where I found my solution for the issue, with which I hope the Testers or ED Team can investigate if possible. Issue: - DCS performance (Single or Multithreaded versions affected alike) drops from regular >80fps to <30fps on busy multiplayer servers (unreliably reproduceable in Single Player) Fix/Workaround: Cause: Instant Replay Feature (I can only be sure about AMD's ReLive, as I dont own an NVIDIA card) Fix 1: Turn off Radeon ReLive feature Fix 2: Set Video Codec from AVC to HEVC. Switching from AVC to HEVC also fixes the issue with ReLive enabled. The issue could also be observed while recording DCS with an AVC-Codec, with the frames dropping to mentioned 12-30fps during recording, only to go up to [my] regular ~100fps - so recording with AVC (ReLive disabled) would still cause the frames to drop. Now, I know that this is strongly related to AMD and their drivers - however I have not observed any similar behavior in any other game but DCS. As I am lacking the tools, I can only guess to what the root of the issue is. I very much hope that posting this bug report including my solution might help out others that have the same issue, as well as get the attention by ED/AMD to maybe check it out. (not going to argue about how useful or sensible an instant replay feature is, thats everyone's own choice and I like saving highlights). If you need logs, trackfiles or other information that I have not been able to include here, please notify me. Thanks.

Es gibt einen AMD FSR Mod (Quelle PCGH News von gestern, dort auch der Link) um es in Spielen zu nutzen die kein FSR nutzen. Es wird einfach nur die openvr_api Datei ersetzt. Über den Editor lässt sich die Renderauflösung einstellen. Mit 0.77 (Ultra Quality) gibt es nahezu keine Einbußen, aber einen großen FPS Sprung. 0.67 gibt nur leichte Einbußen und nur ein weiteren kleinen Performance Sprung. Der Performance Mode geht dann schon mit einem deutlichen Bildverlust einher, sieht aber immer noch mit seinen 50% deutlich besser aus als über SteamVR 75% und gibt deutlich mehr Boost. Vorallem die Frametimes der GPU sinken von 20ms auf um die 10-14ms. Radeon RX6900XT/32GB RAM, i5 6600K@4,7Ghz

Just starting a thread to post my results. Old Build: 5900x Water Cooled (liquid arctic cooler) Asus Hero MB w/ 64GB DDR4 3090 (not liquid cooled) 2 x 2TB Gen 3 NVME EVGA 1200 watt PSU New Build: AMD 7900x3D Water Cooled (Arctic liquid 360mm rad) Asus ROG Crosshair X670E Hero 64GB DC DDR5 6400 Ram MSI Suprim RTX 4090 Liquid X (Liquid Cooled) 4TB Gen 4 NVME (Kingston Fury) 2x2TB Gen 3 NVME Corsair HX1500i PSU NZXT H7 Flow I'll do some tests on the old system and post a screenshot of my settings so I can attempt a similar setup in the new system. All results are in VR on the HP G2 Reverb (Gen 1) Just waiting on the arctic liquid cooler before I can start my build, will run older system tests in the meantime. Not attempting a perfect scientific method comparison but will be as thorough as I have the patience to be to offer the community some semblance of comparison. For context, my 3090 build is severely CPU bound which is why I didn't attempt to get a 4090 for it. Most of the time the 3090 is not over 89% usage and many times is in the 60% usage area while the CPU is full tilt (20% OC'd) Not sure if the 7900x3D was the perfect buy over the 7950 but we'll see. Initial results show the two of them almost head to head, less than 1% difference (7950 edging it by a bit) but no DCS tests I've seen. The reason for the 7900x3D over the 7950x3D is the higher base clock speeds which should result in better single core performance and because its a 6+6 chiplet design over an 8+8 design there should be some extra headroom (in regards to heat) in the 6 chip design to squeeze more Over Clocking out of it as the 8 chip design will generate more heat and DCS won't use them anyway. Is my thinking correct on this, who knows, we'll find out soon enough. In the 5900x vs 5950x (I've run both) the 5900x was faster in my builds. Same was true in the 3900x generation. Either way, the difference would probably be insignificant. The real gains for me will be the extra CPU headroom over the 5900x for more draw calls to the 4090 which I'm hoping I can take much more advantage of than the 5900x did with the 3090. Excited to build this, but not sure when I'll be able to get around to it. Too many projects on the go and this build requires me to build 4 pcs essentially as I have a rotation of parts as I build new machines. (my old machine some parts to my son, and my sons old machine 3900x back to me for the office and my office machine back to one of my daughters etc.. etc..) I love upgrade time, but it will be busy on the workbench for a bit. Some parts sleeping under my desk until the cooler arrives.null

Unplayable in MT & Micro-Stuttering when in Multithreading. (though: ST works fine and stable @40fps!!) FPS-Counter displays CPU bound, but the game still only uses around 40% of my eight P-Cores! (even worse with 16 threads) Bug? I am messing around with this for a few weeks now. Repairs, Shader folders deleted, anything explained in the forum tried etc... no Improvements... SPECS: Amd Ryzen 7 3700X, 3060Ti, 64GB RAM, Quest 2 / OpenXR null #thanks for your help ;-) DxDiag.txt dcs.log
