The situation gets even worse when the cache functions are disabled. With the cache option turned off the texture copies are updated every single time they are used instead of only when changes are made to the ram copies. Thus the stalls from efb copy emulation are more frequent and therefore framerate is even lower. This does not change the fact that the gpu is still producing stalls as well and therefore higher IR still decreases framerate.
Not trying to argue,just trying to understand.
What you said doesn't make any sense to me.
How can gpu produce any stalls when its clear that it can produce much higher fps in all 3 settings tested here ? ( for example 99 fps Ir x2 SSAA x9 )
Why would gpu sudennly be able to produce only 36 fps when efb copies to ram are enabled ? That does not make any sense,because as far as I know,efb copies are not supposed to produce any additional strain on gpu,only cpu/ram.
To me it seems only reason for fps drops are cpu/ram perfomance,which means gpu is not producing any stalls here,or in other words,its not bottleneck,even with 2xir and 9x SSAA
