4K PR0 & 5090
I have a beefy streaming PC, x870e TaiChi, 7950x, 96gb ram, 5090, elgato 4k pro. Gaming - 14900k + 4090.
I'm struggling recording at 1080p60, my gaming pc runs at 480hz, have set capture card as 60hz(least input lag). I play warzone & average 300fps. When i record on my streaming PC at 1080p60, i notice the bus load on the 5090 hits 100%. After a few minutes, the streaming pc starts skipping frames then the sytem freezes & i need to hard reset.
I have my gaming pc colour settings set to: screen 8bit, RGB full colour range. capture card set to 8bit, RGB(tried the other formats too, 422 does the same eventually), full colour & limited same.
i have tried quite a few different set ups on the streaming pc in OBS, set the EDID etc.
Note that the streaming pc - the 5090 is in pcie slot 1 & capture card slot 2, on this motherboard that means they split lanes at pcie gen 5 x8x8, i have a feeling that may be the cause?
Even at pciex8 there should be pleant of 1080p bandwidth?? Just not sure if my settings are wrong or if this is a hardware issue, any assistance would be appreciated.
