imac 2019 and egpu
I recently purchased the 3.00ghz version of the latest imac.
I am planning to buy the razer core 3 along with an amd gpu in order to be able to run some games not so demanding like pro evolution soccer 2020. My question is what gpu to select for windows gaming at good resolution (1440p or better via the 5k monitor) and to be with playable fps.
thank you, i was wondering regarding the performance on the 5k screen since i read in the forum that there is huge performance drop in case of a egpu and windows bootcamp with imac monitor
If you want a stable 60fps, 1440p is going to be the max resolution for the internal display, regardless of the GPU used. I'm using an Aorus Gaming Box 1070 over TB2 on a 2015 4k iMac and the sweet spot for me is 1080p/1152p on most games to hit 60fps using the internal monitor. When I tested with an external monitor years ago, I was able to maintain higher framerates at 1440p. That will give you an idea about performance loss.
I believe the performance hit won't be as bad on external vs internal over a TB3 connection. The one constant seems to be CPU-intensive games really hurt the performance of an eGPU, even when using an external display.
