Hi,Dear works

i have a 1 questions and need you to help to clarify question: I used a PS5 as sink device , input a 4k60 signal , capture a lossness quality video ,1080P60Hz and recorded , i use trdrop to analyze the framerate , trdrop show it will come to 60fps first ,then stable at 57-58 fps , if enable the buffering in OBS setting , it can be 60fps , but i use elagato to try , it could record 60fps no matter the buffering in OBS is enabled or not ,why our capture can not capture 60fps with buffering banned ? does it have any relation with OBS or how could we improve our capture card
?

will be highly appreciated if you could give some advice , thanks

I think I am seeing the same thing. Are you talking about the replay buffer? I get the same results with it enabled/disabled. Looks like I keep getting duplicate frames at a constant rate. I don't see this happening when using AmaRecTV to record with ULY2.

Hi ，could i know what spec does your capture card comes with ? Mine capture support 4K60 input and 1080P@60capture

I have a Evga XR1 RGB that captures at 1080p@60. Seems to work just fine with AmaRecTV for recording. OBS keeps adding duplicate frames and I not sure why.
