iPad Pro M5 jittering and latency spikes

Hi!

I bought iPad for streaming from my PC. I have isolated 6ghz and 5ghz WiFi. PC connected to router by Ethernet. I have spikes from 3ms to 50ms or even more which are causing jitters. I tested Lenovo Legion Go S and its crystal clear. I heard about AWDL or something like that but it seems that nothing help for that which is such a shame as it’s great device. Any tips would be much appreciated…
