After some searching and digging I've not come to a solution.
PC is a AMD 5800X 16GB RAM and Nvidia 3070. TV is LG 4K OLED.
I enabled Red October HQ, and using defaults on for high quality.
I ticked hardware accelerate and video clock to smooth playback.
Audio plays through USB DAC, Teac NT-503 ASIO. Large buffers enabled and buffering set to 100 (up from 50). Besides peak level normalize there is no DSP.
Most videos play fine, 1080 bluray is fine too and upscaling isn't a problem. With this hardware I can go insane on the settings and features in madvr and it will play it just fine.
Some videos however, seemingly regardless of settings, see frame drops and audio stutters quite badly. From the Madvr osd I see clock deviation is high, sometimes 30 or 40%. I dont know if thats a problem perse, but it seems high.
Display settings is set to automatically change mode.
I tried to disable video clock
I tried resetting madvr settings to performance, balance and quality.
The new JRVR plays the problematic videos fine (no osd to verify), but it doesn't look as good (yet) in darker scenes. I prefer some of the advanced features madvr offers.
My hardware should have no problem playing those videos, so I think its just unhappy with a setting that I cant find.
Any ideas, settings I can try to fix this?
Thanks!
