AMD FSR works great for DCS.

[Gunfreak]

Apologies if posted before.

But a modded version of FSR works on more or less all Steam VR games.

 

I left the file default (0.75)

But increased my steam vr resolution in DCS from 78 to 90 and even with 90% it runs better than at 78%.

I don't messure FPS, I just go by feel and it feels smoother,  looks sharper and clearer. I'm tempted to try and pump it up to 95.

 

people who does messure, say they get about 20% FPS increase and a less imperical feeling of better sharpness and smoother experience

Several posts on it; a quick search on AMD FSR ... will help you track them down

I did a search, I only found a post several months old, about the posibilty of it working, Not this new steam vr compatibal modded version.

Can anyone explain why this works so well for my G2/Nvidia 3090/AMD 5950 based system?  I get much better clarity, less anti-aliasing, less stutter.  Obviously, it has to do with some pocket of processing power that DCS does not otherwise use...what ever...it works!

The issue for me is that until now nobody has done a real clarity comparission between FSR and native on VR.

Even though there is a frame time improvement i still can't see if the clarity is placebo or not.

clarity is decreased but with ReShade (https://github.com/fholger/reshade) you get the clarity back...

clarity is very subjective...  (unless you want to use a through the lens camera) ...

As far as I've been able to learn...  You can gain Frame time with this, then gain clarity with re-shade...  but then you're right back exactly where you started with Frame Time...

 

So no you may as well run without them.

I had no impact with reshade when you turn off the color grading.

@M1Combatin FSR the clarity is directly proportional to render scale; I set mine to 0.8 i have had it as high as 0.9 and still had an FPS improvement ... you get more FPS and IMO better quality image than say dropping to 80% in the Steam VR ... YMM and opinion may vary!

 

@JayRoc how exactly do you do that? 

and is that different to just playing with the sharpness variable in the openvr_mod.cfg file ? 

[JayRoc]

From my very limited testing and what i read both work very different.
Reshade not just makes the image sharper but makes the rendered distance ingame sharper.

Even without FSR ReShade is a win for VR players imho.

[speed-of-heat]

@JayRoc agreed, but, how do you turn of color grading with Reshade? to reduce mitigate the perf impact ?

Setting the values to 1.0...its where the sharpening setting is.

Is it beneficial in 2d or just in vr?

First time I tried the AMD FSR Mod, I was not impressed as the drop in quality was too much and I did not even benchmarked it.

I had a second look at AMD FSR mod and found a huge improvement in performance.  From my test benchmark track file, I have a gain of 12 FPS which is a lot. This was with the high quality setting of 77%.  The only issue is that there is a significant loss in clarity and increase in shimmering.  Since I already use Reshade to increase clarity plus 144% resolution in SteamVR, I had the option to pump it up.  To compensate, and since I have such a gain in FPS, I used an additional 20% on the SteamVR resolution slider which brought me back to a good clarity level.  Alternatively I also tried to increase pixel density by 0.1 but seems that SteamVR is more efficient than DCS pixel density (1.1 PD equates to 121% resolution).  Increasing sharpness in Reshade was introducing weird distortions.  FPS cost for extra 20% resolution is not much, about 3-4 FPS.  Next I applied MSAA 2x to get shimmering back to an acceptable level and it turned out even better than expected.  FPS cost for MSAA 2x was about 6-8 FPS.  All in all, I was able to increase other settings such as textures to improve even more. 

Bottom line, with FSR I'm now able to fly MP with max texture quality and reduced shimmering.  The clarity is still very good and acceptable.  I do not use any re-projection and maintain a steady 72 FPS (my HMD has a 72hz refresh rate) even in Syria with a GPU frametime in the low 12 ms.

AMD FSR Mod is worth a try.
