Please see below for the details of DXVA: https://en.wikipedia.org/wiki/DirectX_Video_Acceleration My PC spec: Windows7 64bit WatchOut version: 6.1.6 Using Graphiccard: AMD fireproW7000 thank you After the initial logo screen is replaced by content, anytime a full screen image is displayed by WATCHOUT Display (even if it is nothing but black) it is operating in hardware accelerated Microsoft DirectX 3D rendering mode. If you switch to WATCHOUT Display "window mode" (Control-W) rendering drops back to Windows GDI, switching back to full screen re-engages Microsoft DirectX 3D rendering. However, WATCHOUT does not normally utilize optional video decoding hardware on a graphics card, movies are decoded completely in the CPU and then streamed to the GPU. related: Tip: WMP and QT — disabling hardware accelerated decoding (Exceptions in 6.1.6+: HAP variants on all Display servers, h.264 or mpeg2 only on WATCHPAX variants. These exceptions do use the GPU to decode movies) Quote Link to comment Share on other sites More sharing options...

I understood that Watchout decoding movies on CPU. >Exceptions in 6.1.6+: HAP variants on all Display servers, >h.264 or mpeg2 only on WATCHPAX variants. >These exceptions do use the GPU to decode movies Is it difficult all Display servers use the GPU to decode movies(h264 or mpeg2)?? HAP is good codec, however it consume a lot of HDD resources. Quote Link to comment Share on other sites More sharing options...

Yes, when using the generic Windows DirectX calls, it is difficult to get consistent reliable results from the various vendors cards.
