Some games are just poorly optimized. I have a 3090 and still some games still don't run well particularly when it comes to VR. Try to drop the settings down or even turn down the render scaling if you have to 10% usually doesn't look too bad.
For Skyrim install 'VR FPS Stabilizer' and consider 'cathedral landscapes' for better performance. Also unrelated to performance but if you are playing SkyrimVR I hope you have VRIK and HIGGS.
