Topic: RX 9070 (RDNA4) – GPU stops processing after several minutes
Hi,
I’m using SVP together with MPC-HC and madVR on an AMD RX 9070 (RDNA4). Everything works fine at first: GPU load is steady (~70–80%) and interpolation is smooth.
But after several minutes, the GPU suddenly stops working. GPU utilization drops to idle (0–3%) and all frame interpolation falls back to CPU only, which causes heavy stutter, (Ryzen 9600X )
Important details:
-There’s no driver crash, no TDR, no error in Event Viewer.
-It behaves as if I manually disabled “use GPU” in SVP.
-This happens on all drivers since RX 9070 launch
-The exact same setup works fine on RX 6800 XT, RX 6650 XT, and NVIDIA RTX 30-series.
So it looks like RDNA4 drivers drop the OpenCL context silently after a while.
Has anyone else experienced this with RX 9000 series?
Is there any workaround to force SVP to use D3D11 compute or Vulkan instead of OpenCL in the DirectShow pipeline (madVR + MPC-HC)?
Thanks in advance!
