When I uninstall the AMD video driver the issue goes away however I'm unable then to play games using a generic driver. The MB is a ASUS B450F. GPU is ASUS STRIX Vega 56. I have reinstalled windows and uninstalled and reinstalled all drivers in different order etc inc only installing the AMD video driver and nothing else. I do not have an issue when running Heaven Benchmark software and the problem disappears when I reinstall my old GPU RX290. Any advice appreciated.
Same problem with msi rx vega 56, the problem dissapears when i reinstall my old r9 390
What motherboard are you using?
MSI B350m Gaming Pro with ryzen5 1600
DPC latency problem with dxgkrnl.sys
If you disable the Vega driver in under Display adapter does the latency stop?
I'm just going to RMA my card and my MB. I can find a solution to this tried everything. Spend over $1k on AMD gear only for it not to work.
