Thx for reply.
Try switch from 4xMSAA o 8xMSAA and GPU will raise frequency ?
Something weird, QHD :
0 x MSAA, GPU ~1600Mhz, Mem load ~51%, TBP ~348W, ~280FPS
2 x MSAA, GPU ~1500Mhz, Mem load ~60%, TBP ~348W, ~225FPS
4 x MSAA, GPU ~1750Mhz, Mem load ~66%, TBP ~348W, ~157FPS
8 x MSAA, GPU ~2050Mhz, Mem load ~68%, TBP ~348W, ~99FPS
This is my case : https://www.silentiumpc.com/pl/product/pax-m70-v2/
Yes - my case box is very hot and totally quiet. I need that cause im working a lot and like quiet atmosphere. 3 fans vs 8 fans is big difrent, but quality of fans matter. Simply SilentiumPC fans are not very good, but at 900-1000rpm inaudible. I'm playing games at QHD 60Hz. No need for more refreshrate. I like stable 60fps at maximum graphics preset. On previous card 2080 Super FE GPU reached 85C and started throttling. Maybe 2400rpms is not quiet in open bench, but in my case is nearby acceptable fan noise. Sorry for my poor english.
Best regards !
