Question / Help Extreme Video Lag with Hardware Encoder at 120 fps

[Max Shuyskyy]

Hey,
So I have a GTX 760 and I want to record Minecraft at 120 fps.
My CPU is an i7 4790k, so using x264 will use my CPU and give me worse FPS than a hardware encoder.
If I try to record in 720p 120 fps, it's fine.
If I try to record in 720 240 fps, it lags a lot.
If I try to record in 1080p 120 fps, it lags even more.
Is this because I have an older GPU, or something I'm missing?
Thanks
I also get good frames on all recordings except x264, so it's not my game.

SMH, no one records at 120 fps. Most video services cap at 60 fps so its pointless even if your monitor can handle 120 fps or 240 fps it doesn't make sense to record higher than 60 fps currently. this may change in 5-10 years but for now 60 fps the way to record video.

Using x264 at whatever preset you used, you may have hit your limit of 1080p60 and 720p120. Your CPU is probably not fast enough for x264. Can try UltraFast to reduce CPU usage and less encoding lag.

Try NVENC or intel QuickSync. QuickSync requires compatible CPU (yes: https://ark.intel.com/products/80807/Intel-Core-i7-4790K-Processor-8M-Cache-up-to-4_40-GHz ) and integrated graphics enabled on BIOS/Motherboard settings, with windows intel graphics driver installed.

If hardware encoder (NVENC) works, but x264 does not, the problem is your slow CPU, not your NVidia GPU.
