5700xt fps issues
When I run my external monitor via 5700xt’s HDMI port the performance is really bad, sometimes even worse than when I run the games without the eGPU.
Only when I connect my monitor via the Macbook’s usb-c port I can see a big improvement.
In both cases 5700xt’s fans are running so it seems to be working but I dont understand where this drastic difference in performance comes from.
thanks for replying,
I was struggling for a long time with error 12, I tried every possible fix and finally used the automate-egpu EFI to boot my Windows which worked.
Im running the newest Insider Windows 10 beta release (build 19577) and the latest 20.2.2 Radeon Software.
For the enclosure I use one of the TB3 ports on the left side.
I did some more testing. When running Fallout 4 I get very nice 60fps on ultra settings 1440p, regardless of whether I run it via hdmi or usb-c.
The problem definitely occures when I run Half life 2. On 2160p via USB-C I get a steady 55-60fps, while via HDMI framerate drops to only 25-30fps. Weird, maybe it’s got something to do with HL2 running old DX9.
@bartek_uchanski, Have you tried setting the external monitor as the only active display and disable internal display?
Yes, my MacBook screen is turned off. I tested some more and I can confirm that problem seems to occur only in HL2 (maybe also some other older games). I Heard there is some problem with 5700XT supporting DirectX9, maybe that’s the reason.
