Uninstalled OpenFSR and Shader mods. Surprised by the results. 511.23 3070 RTX

Upgraded to 2.7.10 and performance is even better now, +2 avg fps. Less stutters

Personally I tried OpenFSR and decided to remove it.

For instance, with SteamVR SS at 100% and OpenFSR at 80%, you get the same performance results as SteamVR SS on 80% but you add another layer of upsampling and artifacts. For the SteamVR SS at 80% gets me better image and it is easier to control, debug, and tune.

Something is upscaling the image -- maybe WMR I guess?  At an effective PD of .8 or .9 WMR doesn't do a terrible job imo.

I myself have always refused to run any Mods. Just a personal preference thing. I find though I spend way more time flying than tinkering and I kind of like it that way. And the sim is really gorgeous to me in VR.

FSR should work best, I think, if your Steam and DCS settings combine for a resolution of about 140%, depending on the headset.   For a G2, we are talking about a 3100x3100 image.  Anything else dilutes the effect of FSR (because WMR is going to be scaling the image after FSR is done with it, resulting in Lord-only-knows-what)

My recommendation:

1.  Start with Steam global resolution 100%, per-app 100%, and pixel density 1.0.  Go for a fly.

2.  If your system handles this with ease, you get to try antialiasing.  You can use supersampling or MSAA, your choice. 

3.  On the other hand, if this kicks your hardware's butt, it's worth trying FSR.  Keep your Steam and DCS settings exactly the same, let FSR do the scaling.  I'll bet you like it; I find it basically impossible to tell the difference between native resolution and FSR running at a RenderScale of 0.8 or better, on the G2 at least.  There's gonna be some jaggies though. 

The extent to which the FSR mod is better than merely dialing down your settings, and letting WMR handle the scaling, is debatable.  I don't think WMR does a half-bad job meself.  Try one against the other and see which one you like best.  If it's all the same, I agree with the sentiments in this thread: keep it simple.  

4.  If you have to dial your effective pixel density much lower than about 0.7 -- regardless of whether you're doing this with FSR or with any combination of Steam or DCS settings, you might need a new GPU.  (Or a new HMD... I'd rather drive a Quest 2 well, than a G2 poorly).  Put it this way, an effective PD of 0.5 looks pretty gross any way you cut it

Sharpening is another matter altogether.  It will not eliminate jaggies, will not improve performance, and it introduces its own artifacts.  Aesthetic effects only.

Speaking of aesthetics, I'm not at all sold on the idea of combining undersampling with MSAA.  It's fairly pretty I guess, good for sight-seeing, but isn't good for gameplay and IMO would be easier to just buy a copy of MSFS or XPlane.   The combination of supersampling and MSAA is a different matter.  Research suggests that's the optimal combo, but not having a NASA supercomputer, I wouldn't know.

Net of everything, I'm led to the conclusion that there is no such thing as a free lunch.
