There is a big issue with 4K HDR Recording with OBS. On BF 2042, with these impact on the gameplay, it s littetterally unplayable which is absoluetly not the case with ShadowPlay.Įven if ShadowPlay records in VBR, the capture is recognized as 80 Mpbs 4K HDR by MediaInfo and the Average Bitrate is pretty close to that value. Result is that nothing change, the same frame drops are occuring, the same huge lags, the same tearings and slowerings, the same sudden encoding overload while the recording settings are pretty basic and usual recording settings used in Nvidia ShadowPlay with no issues at all. These are the logs from 2 test recording sessions in 4K HDR with the same settings except the Bitrate which are : for the 1st 80 Mpbs AND the 2nd 40 Mpbs.

You will notice the that the frames are very irregulars and that suddenly, when a lot of ennemies are close, big frame drops are occuring.

Here are the Logs if you want to study them. Click to expand.Especially for this issue and following your request I remade a test capture session.
