If you really think it is something odd happening after three minutes do not look for issues in madVR, nothing changes in madVR after three minutes. That would be due to overheating or power saving options or similar. Is Optimus behaving badly again? That tech does not work very well in my experience. 
Monitor GPU clocks while watching madVR, hwinfo is a good tool.
Edit: try running without any pre/post filters with show render steps so you can see all of them. Is anything obviously very slow? |
Using
fewer pre/post processing filters (image corrections, not upscaling/downscaling) does
improve performance by about 10ms but it's also very important for good video quality at low-res meaning disabling kinda
defeats the purpose of this whole setup.
Tried
ordered dithering and it DOES improve performance without any visible quality loss but by only about
5ms so
not a huge gain.
Clock is stable so not an issue but the
GPU is hot (~85ºC - hot but not overheat hot) when madVR is working (with 70ms render time). But then again, that's probably due to the hardware limits and not so much Optimus drivers. I should also probably mention I don't have energy saving mode enabled.
Now that I can see the rest of ShowRenderSteps the composition of render time (~65ms because ordered dithering) is as follows (approximately):
- Image corrections - 10ms
- Deblock - 8ms
- Chorma Upscaling - <1ms
- Debanding - 2ms
- Deringing - 7ms
- NGU Doubling - 9ms
- Jinc Upscaling - 10ms
- Image scaling X+Y - 5.5ms
- Subtitles - 7.5ms
- Final Step - 3ms
What do you think I can afford to remove / compromise?
