Hi!

Congratulations, beautiful app!
It works great with H.264... however, I have issues with HEVC Main, which is very very slow at the same bitrate...

PS5 firmware 4.03
Prosperolight 050

Hi @cryptoalex74 ,

Can you try the latest version? It should have some performance enhancements.

Once again, I'm experiencing severe frames drops with HEVC... strangely enough, none with H.264!
I'm also experiencing a lot of network dropped frames, but only with HEVC..I tried it over Wi-Fi and over LAN... same results...
It's as if enabling HEVC would interfere with the network!

thanks
alex

Thanks for the feedback. I am going to do more testing - surprisingly enough, my recent successful tests were with 4K120 FPS on HEVC + HDR, using Hollow Knight as the test game (one of the few games I have my GPU can handle 4K120).

Do you own Hollow Knight by any chance and if yes, could you also use it as a test for benchmark purposes?
