WipeUout

Ok, here we go. First thanks to @Sr. for the advice about doing a clean driver install, I did that and it worked 100% at start. First run was terrible with a 15 FPS drop, lots of stutters, repeated twice with same results. I was suspecting conflicting problem with reshade or vr shader. Then tried vanilla and saw a 5% gain right there. Re-installed reshade_sharpen_color and FPS gain was up to 6.5%! The conflict was with "VR Shader mod for 2.7.12.23362", the new AMD driver does not play well with it. I have not tried with SIMPLEX as my FPS gain with it is now negative since last OB update. Not using VR Shader ended up by a positive gain nevertheless as I was getting a 4% FPS gain with it. So my net gain with the new AMD driver is about 2 FPS but simplifying things as no need to uninstall/re-install this mod again, and suffer for long waiting time when shaders need to be re-compiled. Positive overall. Not a great gain but will be significant for people not using a shader. More info: As I am trying different modules and terrain, I find that some occasional stutter happens. I think the card's shader cache is being re-populated along the way. If I replay the same mission, the stuttering goes away.

I will be back home in an hour or so and will try then.

Anyone tried the new AMD preview driver? They advertise double digits improvement in DX11 games...

Anyone having low or negative performance with VR Shader SIMPLEX? I used to have a slight gain of 2-3 FPS but as of the last OB and 3dmigoto update, I get a little drop of 0.5 FPS.

I use a 5k Super and get very stable 90 FPS in SP, and also in MP unless flying over dense city but even then, the drop is around 80 FPS which is not bad at all. The 5k Super has 90hz as the lowest refresh rate. When using reprojection, I get ghosting that is not acceptable to me. Fortunately, I can achieve 90 FPS in most of scenarios and it is butter smooth, thanks to my 12th gen i7 and 6900XT. I would like to improve resolution and I am considering going for the 8kX. I am not sure if it can keep up 60 FPS and avoid using reprojection. How is the ghosting when reprojection is enabled?

Many thanks again @lefuneste01! Issue not showing anymore. Tested in F-16, F-18, AV-8B, A-10A,C,C_II. ...and F-14 also.

Sure, if it can help.d3dx_user.ini

Here are my DCS settings: Discard gamma setting I was just palying a night mission, my usual setting is 2.2

After playing the campaign twice, I think this is a very entertaining and fun campaign. It offers various opportunity to use different weapons in day and night environment. Liked very much the "movie" experience with dramatic music kicking in at crucial moments, very entertaining and different. Only suggestion would be to offer cold or hot start, just to shorthen a bit the mission time. Looking forward to another campaign!

The first post leads to the user file download page on the DCS site. This is the file I used : 3DmigotoDCS_VR_16.0.zip I was using 16.0.1b (21 April) before the latest OB update and the issue was gone. I was a bit confused with the version I downloaded, was expecting a version higher than 16.0... Is it the right file?

Same issue with the A-10C_II: Deleted all .bin files, no joy: Attached is a track file from an A-10C in Caucasus. Ghost Cockpit in MFD (A-10C).trk

Dear @lefuneste01, the cockpit ghost seems to be back both in Maverick and TGP screens in the F-16: I tried to adjust MFD settings (sharpen and luma) but without any success. If you have some spare time this coming weekend... This does not impair playability though, I am still able to search and lock targets.

Thanks @lefuneste01 for the 16.0b1 update, the cockpit mask/ghost is not showing anymore. I just started using 3Dmigoto a few days ago and the features are really nice but I have a hard time understanding how FXAA works in relation to the variables we can play with. I understand that you can't achieve as good a result as using MSAA but if you have any hint on which setting will get maximum anti-aliasing this would help.

DCS uses DX11, not DX12.

This is one factor, and there are many more such as single core utilization. Hardware Unboxed made a very interesting comparison between the 5800X3D and the i9-12900k, see it here`: If you look at performance at 4k, there are a lot of instance where the games are GPU bound. For DCS in VR, it is even more demanding than 4k. The 5800X3D is definitely very impressive but will probably not have a big impact if your GPU is the bottleneck. Interesting also are some titles benchmarked are single core, just like DCS. The 5800X3D is a good solution if you already have a AM4 based system, as long as you can find the chip and buy it...

Very important factor to take into consideration before changing your CPU. You have to understand where you are and what can improve your system performance. Consider the following diagram which I call the DCS VR Settings Game: Analyzing your frame times for both CPU and GPU for a specific level of details/quality will help you see what kind of benefit you can gain from upgrading the CPU. When setting our graphics quality level, we all try to stay within an acceptable framerate for most of the time. In order to achieve this, we set things up in order to have the CPU frametime average at a certain level that will be equal or bellow what is takes to generate the target FPS. The GPU generate frames from data provided by your CPU. Ideally, you need the CPU frametime to be the same or lower than the GPU frametime in order to fully use the potential of your GPU. In this situation, you are GPU limited and it is what most of us experience in VR as it is very demanding to pump out all those pixels in such large amount. We tweak settings for countless hours in order to be in this situation where our GPUs are being used to the maximum. At one point, you may increase the performance of your CPU by overclocking or upgrading but eventually, it is the GPU that will not keep up. At that point, not matter how low your CPU frame time is, the average FPS will not change much. If you experience very high peaks in your CPU frametime, then it might be helpful to upgrade but It will not increase your GPU`s performance. You have to analyze what is your particular situation by monitoring your CPU and GPU frametime. fpsVR is a great tool for this. Understanding where your bottleneck is will guide you as to where to invest next and it might be a better GPU that is needed.

I would be very careful and wait further reviews, specifically with DCS. The single core performance of the 5800X3D is not so good, it is actually less that the 5800X. How much a big cache will impact in DCS is not known now but could be negligible. DCS graphic engine requires fast single core performance the way it works now, and there is not official timeline when the graphic engine will be upgraded to multi-core like in most modern games.

This can also be done if you have a spare computer/laptop to use as the "DCS server". You don't need to have a beefy one and not even a good GPU. Just install the server version, hook it up on you local network and there you go. The server version has all the maps, no extra cost. You can setup a network drive on you "play" computer pointing to the mission folder on the server and do your ME work without having to jump from one pc to the other. I also setup a teamviewer session from my "play" PC to the server, this way I can pause the mission remotely without having to get up to go the server. Squeezing every bit of performance possible.

If you use fpsVR, what is happening with your CPU and GPU frametimes when you see a drop in FPS? This might help rule out (or pinpoint) CPU or GPU for issues.

DCS uses about 10-20% of your CPU power. This is because only two cores are being used instead of taking advantage of the multi-core capability of modern processors. There is a plan to modernize the graphic engine of DCS to take advantage of this technology but we have no idea when this will come. As of now I would say go for the CPU that has the highest single core performance to ensure you can generate all those pixels to your VR headset. The Single core speed champion now is intel's Alder Lake, or the 12th generation. I just upgraded to a i7-12700KF and it significantly improved my experience. It did not made the GPU go faster but gave it some extra breathing room, especially in MP.

What are you running DCS from? SSD or M.2? and what is the size of your page file also? It sounds like you are getting out of memory or you have a bottleneck in your storage system. Might want to check the health/performance of your drive or how much space is left on it. Having a dedicated M.2 drive for DCS only helps a lot. Tried all possible resolutions and no luck. I can't get RSR to activate. Seems that DCS is not running in a full screen mode to allow RSR to activate.

Yes and FPSVR is a good tool for this. I went from a 9900K to a 12700KF and definitely saw an FPS improvement in scenarios where my GPU was held back by high CPU frametimes. If you GPU is already taxed 100% (or close), a new CPU will not help much. In general, if you see CPU frametime same or higher than GPU frametime in FPSVR, then consider upgrading your CPU. Just make sure that the new CPU has high single thread performance which is the critical factor for DCS. Alder lake CPUs have the highest single thread performance.

I am no expert on G2 but as for your DCS settings, some changes could improve your FPS. Lowering the clouds will not change much the visuals in VR. You may also put terrain object shadows to off, this will give you a good increase in FPS. Anisotropic Filtering does not improve much the image quality but could give you more FPS at lower setting. Civilian traffic also impact your FPS, consider turning it off. You may also get more performance by using a shader. I use "DCS VR Shaders mod for 2.7.11.21408.1" which improves a bit the performance. A lot of factor will cause a drop in FPS such as background scripts and smoke/explosions, flying over/towards dense sceneries. Reducing your scenery details factor might help too.

So I finally pulled the trigger on an i7-12700KF. Very good match for the 6900XT. The first few benchmarks I did showed a decrease of 2.5 milliseconds in CPU frametime. The improvement is most noticeable in multiplayer, not needing anymore to decrease my settings. Overall stability also much better in busy scenario with lots of smoke, AI around and scripts running in background. Having a 12th gen CPU gave breathing room to the AMD card and a pleasing stable 90 FPS in my Pimax 5ks HMD. I have to update my hardware description bellow now...

Is there any way to activate/toggle reshade in VR without a controller?
