Specs: i7 8700, 3060ti, 16gb ram(don't know mhz)
The problem only occurs in warzone, reaching barely 100fps at lowest settings. When I open task manager, CPU:67%, RAM:99% and GPU:40% usage. It seems that there is a problem in rams but cant pin point it.
Your help is greatly appreciated.
I have 32GB RAM and Warzone consistently uses 13.5 GB. Total system RAM usage = similar to what the OP is getting.
As for the FPS issue - you may have to go to your adv_options config file and adjust the video RAM value to 0.85 or 0.9 - it may be set too low and thats why you are getting low usage specifically in Warzone.
