VR STILL NOT FIXED

@ChadSquadron88 The 461.33 Nvidia Hotfix drivers helped a little bit for me, they got rid of some intermittent stutters and I can play smoothly with maxed out settings (except Volumetrics which need to be on Medium or lower for the game not to crash upon loading the Yavin map in VR) and 100% Supersampling/Resolution Scale at 60Hz on my HP Reverb G2 and RTX 3090/Core i7 9900K/64GB DDR4-3600 RAM and NVMe SSD now. 90Hz above 60% Supersampling is still a stutter fest, though. So yeah, hopefully a Squadrons Patch can fix performance in the future.

As for Nvidia Control Panel settings, you can try setting the following for Squadrons:
Texture Filtering - Quality: High Performance
Anti-Aliasing: Application Controlled
AntiAliasing-Transparency: Off
Vertical Snyc Off
Threaded Optimization: Off
Power Management Mode: Prefer Maximum Performance
Virtual Reality Pre-Rendered Frames: 1
Virtual Reality - Variable Rate Super Sampling: Adaptive or Always On

Some general tweaks you can try to improve performance:

1. Right-click on starwarssquadrons.exe, Compatibility, then tick Disable Fullscreen Optimizations.

2. Open your shortcut or launcher options and add  -USEALLAVAILABLECORES -high to the end of the shortcut and/or launch options.
3. Disable Game Mode in Windows 10.
4. Right-click on the Desktop, click Display Settings, click on Graphics Settings and under Graphics Performance Preference select Desktop App, click Browse and select starwarssquadrons.exe. Then set it to High Performance. While there, you can also try turning Hardware-accelerated GPU Scheduling to Off if it's on (requires you to restart Windows).

5. Disable any overlays you may be using (Origin, Steam, RTSS, Xbox Game Bar, etc.).
6. Make sure you aren't running any monitoring Software (MSI Afterburner, RTSS, ASUS GPU Tweak, EVGA Precision, fpsVR, FRAPS, etc.), since that still causes issues with Nvidia Drivers and can decrease performance overall.

7. Minimize Squadrons, Mixed Reality Portal, SteamVR, Oculus or any other software you have to be running for the game (close any not-needed software) and click on the desktop while you're playing Squadrons in VR as that seems to improve performance.

8. Disable or Enable Motion Smoothing/Reprojection and Advanced Supersampling and see if one or the other works better for you.
9. Run your HMD with a lower refresh rate.

10. Set your Windows Power Plan to High Performance or even Ultimate Peformance (if available on your PC).
