i7-6850k ? Recording at 4k @ 60 fps possible ?

post #1 of 7
Thread Starter 
I try to record my game play videos with the OBS studio but unfortunately my 6700k can only record videos at 4k with only 30 fps, can someone guide me if i get a 6850k would i be able to record 4k videos at 60 fps with no hiccups what so ever ?

Use Geforce Experience. With a 1080/980 Ti, you can record at 4K 60 Hz no problem.

Since you're using OBS, why not just use NVENC on your 1080?

No need, OBS can do the same thing, but with more customization.

Shadowplay has close to zero performance hit. Using a CPU to record a video is not an optimized approach, specially at 4K..

So it is exclusive to ShadowPlay and NVIDIA Grid systems powering cloud gaming servers.

OBS can use the GPU's encoding block just like shadowplay can. Just switch to NVENC, it should be somewhere in the options.


The AMD version gives you a ton of encoding options to play with if you like that kind of thing, I assume the Nvidia version does too.

Ok so I read more about this. You're right, the non encoding parts have considerable CPU overhead that shadowplay doesn't. I didn't know that.

Still, just using NVENC instead of CPU encoding at 4K in OBS would be a massive boost.

However... since shadowplay isn't working, I suspect there may be something wrong with OP's drivers.
