According to https://www.svp-team.com/wiki/GPU_Compatibility a GT430 should be capable, but GPU accerlation is way to slow. I recognized that if disable GPU accerlation CPU usage is around 40-50% and GPU Utilization is @ 30-33%. If I enable GPU accerlation CPU usage drops to 10% and GPU Utilization is below 10% and video playback is hard desynced and stuttering
(Video Engine Utilazation is always @0%)

Something wrong with my system or is the information about the GT430 just out of date, and the card is to slow for SVP 4.x?
But I'm absolutly confused about the CPU/GPU utalization. Why is GPU utalization higher if I disable accerlation, and why is GPU utalization just around 10% if accerlation is enabled (no wonder it lags/stutters/desyncs as hell).
Best regards
