I saw something else someone said helped a little if you wanna try it I haven’t gotten the chance yet.
Log into the game. In the chatbox type
/console cvar_reset gxallowcachelessshadermode
then
/reload
or if you have advanced interface options
Search for CVar Browser
Search there for GxAllowCachelessShaderMode
Change value to 0
In-game chat type /reload
