Madvr stutters on 720P with DSP convolution

<< < (3/3)

mattkhan:
Scaling is on the GPU which is where the additional stress should be for switching to 720p. Decoding might move to the CPU depending on the system and setup. What source of load are you thinking of that would be contingent on resolution/source?

The OP needs to give more detail on load on the system in different conditions to comment further really

Franky:
Thanks for your replies.
I have a MSI RTX 3060 Ti 8GB and a Kaby Lake I5 7600 3.5GHz cpu with 4 cores.
The cpu load is about 42% with the individual core load attached. No CPU problem I think.

When I switch all scaling to Bilinear, audio stutter remains. And Madvr stats show very easy load (attached). CPU load about 20%.
The audio stutter stops when I deactivate convolution and the cpu load is 18%.

mattkhan:
2 cores are rather heavily loaded

Why are you using a large decoder queue?
What settings do you have for your audio buffers in MC?

I would experiment with those settings to see if it helps, e.g. reduce the decoder queue size first then look at bumping up the audio buffers

Franky:
When I use a small queue and play with all audio buffers
- play from memory
- prebuffer size
- Wasapi hardware buffer
- live latency
I have tried all kind of variations in buffer settings, but nothing works.
Only when I switch of convolution erverything is fine again.
Even with simple bilinear scaling and very low cpu loading the audio stutters. I don't understand it. Feels like a bug to me.
