For context. I just updated bios (to fix another issue) and enabled DCOP 1 + PBO and I saw a big improvement to performance over DOCP 2 on the old bios. However I go back on my pc the next day and the performance is reverted. I cannot see what causes the performance increase. The only difference I can see here is that for some reason, when the performance is worse it says I have 31gb of RAM but when it is good it says 32gb. No BIOS settings have changed between screenshots.
