Question / Help Game stuttering at higher video settings (720p@60/1080p@30)

As I said in the title, it's not so much the stream but the game stuttering, even in preview mode. The games I tried so far were both 2d, low requirement games, that run easily on my machine otherwise. Tried between 2000 and 4000kb/s bitrate, CBR on and off, window and game capture. Any Ideas?

Re: Game stuttering at higher video settings (720p@60/1080p@

What i see here is that you get lagging frames when u use 60 FPS. Its not much but seems like your PC is not handling 60 fps very well.

Also, avoid using VBR and Quality of 10. U should go for CBR with opencl=true custom parameter for x264 and try again. Maybe u can get some encoding to be offloaded to GPU a bit to save up some CPU cycles.

After u did that, post your finding again...

Re: Game stuttering at higher video settings (720p@60/1080p@

Thanks for the reply. Well, I tried adding opencl, and nothing changed. Disabling Aero seems to fix it almost completely, lagging frames down to 0.01% which is generally ok, it didn't occur to me to try because reading through other threads, I never saw anyone suggest it. I just assumed it couldn't affect anything.

Also, you figure some cpu oc'ing could help at all? I had some stability issues when I first built the system, and I never got around to it, but my 2600k could go up to say 4.3ghz without any issues. It seems counter intuitive to me that it would help seeing as all this never gets the cpu to even 30% load ever, but maybe?
