I have been tinkering away for a while and had been noticing a large decrease in performance when enabling aliassing at any level, when having MSAA at 4x the fps drops to only 30% of what it was without MSAA enabled. the same goes for SSAA.
Whilst the frame drop is occurring, the CPU and GPU aren't nearly maxed out with a 60% and 40% load respectively.
the framerate goes from 60 to about 18-20, it's constant.
I have been stresstesting the hardware, with furmark for example, to see if the hardware has any issues... the pc performes well and as expected.
Has anyone got any idea what would be going wrong internally, or in regard to my hardware? i suspect something going wrong between dolphin and the driver.
Ayway, ways to reproduce:
turn on MSAA at any rate
Start your mario kart wii pal
vsync, HLE or LLE, IR 2,5x. all don't seem to make any difference with this issue.
Tried both lates stable and béta AMD drivers.
Could be of influence:
AMD r9 270 GPU
Intel Pentium K G3258 @4,2GHz dualcore, hasn't got hyperthreading.
Dolphin 4.0-6759
game i found most affected: Mario kart wii PAL, but every game is affected whilst the GPU is not nearly being pushed to the limit.
