Title: ROHD performance
Post by: guer_j on June 14, 2017, 10:32:25 am

So I finally started looking and playing a bit with the video settings in JRiver. Tried the RedOctober HQ setting and , yeah, it looks much better in my BenQ projector.  My PC is:

Processor   AMD A10-7800 Radeon R7, 12 Compute Cores 4C+8G, 3500 Mhz, 2 Core(s), 4 Logical Processor(s)

The issue is my CPU runs at about 32% 'ish and I get the occasional drop frame every few minutes or so, which is not horribly bad but annoying enough.
I guess my question is if getting a dedicated video card might help or would I need to get another motherboard/CPU? Any tips? I unchecked the interlacing on madVR and that seemed to help a bit.

You find information about the capbility of the A10 GPU here:

Get GPU-Z and look how the ressources used by the GPU are utilized.

A10 is sensitive regarding memory performance. Do you use 2133 RAM and two slots?

Is hardware accelarion under video option on?

Thanks  for your reply... I only have one slot  8gb memory @ 1600MHz DDR3.   

When I uncheck -> "Harware accelerate video decoding ..." the  video performance is actually better so looks like it's not using the GPU.   I'm going to look into GPU utilization today  using GPU-Z and see what I find.

AMD A10-7800 has a video passmark of 895. Subtracting ~25% because of 1600 MHz Memory -> effective passmark of 671 which is not very high. Intel HD 4600 has something ~ 700. HD 4600 is very old and e.g. an GTX 1050 TI has a video passmark~ 6500.
I assume you have an FHD Monitor. You could not expect much from your GPU using ROHQ.
YOu could also check the rendertimes by pressing CRTL-J during video playback.
