I started this topic to track and discuss challenges with getting the best performance out of the system. I usually test each setting a couple of times. 27-1-2025 Nvidia 571.96 DLSS 4.0 Installed the new drivers. 25-1-2025 Adjusted GPU Overclock Increased CPU PBO Scalar and reduced some of the GPU overclock to further increase fps and frametimes. Time will tell if it also stays stable on the MP-servers. 18-1-2025 Clean W10 Complete reinstall of W10 returned another 5fps and better frametimes. Over the years the system got bloated with all sorts of traces from old hardware that I upgraded (2x GPU and CPU) and software that I tried and not fully removed. The system is snappy and clean again! I considered W11, but there are too many bad stories out there, no clear advantage for AMD and GUI modifications with taskbar etc W10 is easier. The only thing I still notice is that it seems that when I hit the FPS limit some sort of trouble in FPS and frametimes appears. When I stay a bit below 90, like 88fps, it is more stable. 27-12-2024 Current Overclock settings 64GB ----- EXPO: ON (timings default as stated on the DIMMS) 9800X3D ----- Turbo Game Mode: ON PBO: +200 Curve Optimizer: -20, FCLK Infinity Fabric: 2200 UCLK DIV1 Mode: UCLK=MEMCLK, SCALAR 10X 4090 ----- Core Voltage: +100 Core Clock: +120Mhz Memory Clock: +900Mhz, Fan: Power Limit 133%, Temp Limit 84. This GPU overclock is stable and gives me 4-5 extra FPS, even when i am CPU bound. My setup Windows 10 - latest version - Windows 11 will not happen until I will get serious latency advantages. Motherboard: ROG STRIX X870E-E Gaming WIFI Systemboard VR Headset: Varjo Aero SSD for DCS and Windows, separated DCS Settings Most are set to the max. SSS, Secondary Shadows, SSAO, SSLR are disabled; they do not bring much visually. Visibility Range Extreme. I have Visible Range set to High. Increasing this further is not bringing much visual improvement and really takes away performance. MSAA Mask Size 0.42 is my sweetspot. Testing Setup and approach My Windows has been heavily tweaked and optimized and I am currently still running the same Windows I started with 5 years ago. I upgraded my systemboard, CPU and GPU a couple of times but did not reinstall Windows. I think at certain moments in the past I even went too far with tweaking and should have dialed back and better register what I was doing. So a clean install will be somewhere in the near future because I am certain I have left quite some performance on the table. For the basic quick test of setting adjustments or hardware/software updates I start a the default A-10C mission Runway Startup on the Marianas Map. I use Marianas because this mission is quite demanding and quite stable almost from the start with AI not doing much. I let it run a couple of times for 20 seconds and track the performance with CapFrameX to calculate the average FPS, 1% and 0.2% lows of the runs. Many other missions give me 90FPS, so adjusting settings with such missions will not give me noticeable visible differences. If I want to visually see the performance I open up the the FPS overlay inside DCS. I sometimes also open up the new XRFrameTools application to visualize my frametimes. Once a setting looks pretty okay I log into our Wing's Multiplayer server, startup OBS recording and give it a spin to see how it goes. I usually get 90FPS flat in this setup, while running OBS recording. Testing log From now on I will start adding my complete testing logs to this main posting. Where relevant I will add charts to visualize the difference between certain options. Certain tests were eye-openers. It was/is a dreadful process going through all the settings and quite a few settings were insignificant in my case. Frame Times, average FPS, 1% and 0.2% Lows My main goal is to find the ones that will bring more stability (reduction of intrusive stutters) and performance (increase of FPS/frametimes). Sometimes it is like searching for a needle in a haystack. Seeing the settings that made a difference might bring quick wins to others as well. Overall the average FPS is not improving that much by all the tweaking, it is easy though to screw up your system and reduce FPS. But once the FPS are pretty decent it is hard to get substantial improvements. My biggest wins are with the 1% and 0.2% lows, reducing these give a much better overall experience than to have 1-2 more average FPS. The overall FPS can be high, but when you have a few microstutters here and there it is very annoying and for me breaks the immersion in VR. Caution Please be careful, not all what works for me might work for you. Do everything at your own risk. I had some crashes, especially with the overclocking, so always make backups and restore points. I also don't have my overclock software start automatically anymore when tweaking, because that also caused an issue once causing me to keep rebooting into a crashing configuration. null null null

Hi DCSimmers, as the title says I'm experiencing issues with my recordings in DCS. The output file can never be as smooth as my in game experience. There are frames dropped, intermittent stuttering, lagging issues. It can be good for 2-3 minutes and then slightly stuttery and back to normal, repeat... Nothing I can use to create content for DCS. I've spent (6+) hours tinkering with all the settings you can possibly imagine. Last resort for me, trying to find help on this forum. My PC Specs : - Alienware AW3821DW 37.5" WQHD+ (3840x1600) - ROG_STRIX_Z790-E_GAMING_WIFI - i7-13700K - 64Go of RAM - ASUS TUF GeForce RTX 3080 Ti O12G GAMING - Windows 10 Pro - DCS drive is an NVMe M.2 as the drive I record my OBS files on. My CPU Cores are unparked (noticed a real gain in performance in MT DCS after that) with QuickCPU. Winwing Orion 2 + Ursa Minor + Track IR 5 As I don't have the biggest GPU I've capped my frame rate to 60 in DCS (and/or NVidia Settings) and it's been running really smooth (even on MP servers). As I've said above, I tried tinkering with a lot of settings in DCS, OBS and NVidia Control panel. Here are my global settings at the end of the post. As I have a G-Sync Monitor I've noticed that VSync doesn't seem to add a lot to the smoothness to my ingame experience (maybe a little bit less tearing on rapid head movements, but not much). I tried disabling G-Sync and went for "fixed refresh rate" but had to activate VSync to get a proper ingame experience. But my recording remained choppy/stuttery. I tried VSync both in DCS and NVidia Settings. I tried Frame Rate capping both in DCS and NVidia Settings. I tried every possible combinaison of OBS Settings you can possibly imagine (CBR, CQP, you mane it...). Sometimes the result is awfull both in game and for OBS recordings, sometimes its better and I'm back to a normal ingame experience, but in the end OBS Recordings are always stuttery/choppy. No matter what. Same thing happens with NVidia ShadowPlay as well. There must be something I didn't try and you can help me with. Also, I'm planning to find a second hand RTX 4090, do you think that it can improve of fix this kind of issue ?
