Stutter every 1 second #67

Open q3wzeck opened 1 week ago

Hello! I've been using this plugin for about a year and thought I had some wrong settings in obs or something, but today I discovered this: when i start obs, i have weird 1-frame freeze in game (cs2 or any other 3d game) every second. i launched obs in safe mode - everything fine. then i removed replay source plugin, launched obs normally and had no stutters anymore. this happen even when i don't capture game, i tried with empty scene too. maybe you better know what this plugin do every second? hope it possible to fix or optimize. no errors in log etc.

How do you detect the 1-frame freeze? Do you also get it with the plugin installed but no replay source existing? What is the resolution and framerate of the source? How long is the duration of the replays? Can you provide an OBS log file of a session with the issue?

thanks for reply! i detect it with eyes. smooth fps is very important in cs2, i think everyone can feel it if something goes wrong. tried to remove plugin layer from scene - stutters gone. added it back - stutters back too. all scenes in obs are 1920x1080, 60 fps. game runs at 3440x1440, but i tried other resolutions. replay duration 6 seconds. log: https://obsproject.com/logs/OTpjLqVfGH9vB0F1

3440x1440 at 60fps for 6 seconds is about 7GB of data. If you have the last replay and capturing a new one, you come to about 14GB of data. I think you're graphic card driver doesn't want to keep all that data on the graphics card and moves a part to ram every second.
