Bug ID: 204947 Summary: Scatter Gather not working properly on Raven ? Product: Drivers Version: 2.5 Kernel Version: master Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: haxk612@gmail.com Regression: No
I have Acer Nitro 5 with Ryzen 5 2500U and RX560X. The dGPU is wired into iGPU (VEGA8) so we have to use PRIME. I reported a bug earlier about tearing in games. I have been told i have to wait for scatter gather support. Now that its in place i tried it to my suprise tearing was still there. Only way to get rid of it is to use TearFree which intrduces stuttering at even 60fps.
If you need anything just tell me i will be happy to provide any logs or that sort of stuff.
