[Various issues] Grass looks weird with DLSS

The grass looks blurry/flickers whenever I turn DLSS on no matter the setting (Quality or Balanced). Please see the screenshot attached (it's more noticeable in motion but all I can upload is a photo).

Also please see the other screenshots for two other bugs. At one point my knife as sideways after sliding and in the other, my camera was stuck where I died and it only got fixed after I redeployed.

On top of that the performance has gotten worse since the beta, the beta used to run very well (I had constant 60-100 fps with everything on low except for textures on high and ambient occlusion on low) but now the game drops to 40 fps at times.
