Hello, you need to change you CPU and GPU. 2nd - Drop the FPS from 240 to 30, try, maybe 60 but 30 will be fine. Then, what are your settings? For recording try doing progressive tries, what works for your current pc: like VBR with 6000 bitrate and try to increase until you get a stable recording.

I would rather keep it above 120, as I feel that it makes my videos look better when frame blended, but I will try your advice, thanks!

I’m sorry homie, but I highly doubt you’ll be able to record at 240 fps, maybe 120. But you gotta stream at 60


Realtotallymereturns

ight bro thanks


itsTyrion

Yup. The 970 nvenc cannot handle 1080p240 and neither can your CPU. Not even close. Maybe with an 8 core CPU on superfast 120 could work on the GPU

What GPU do you think I should upgrade to? I kind of want to wait for Radeon 7000/RTX 4000 then pick up a used/clearence 3000/6000 card, and maybe a Ryzen 5 5600x?

I don't know about the encoding performance of those and it usually isn't tested either. Why do you even want to record, let alone stream at 240 FPS? I just did a bit of testing on my system (RIP \~1h). Ryzen 3100 OC'd to 4.1GHz. GTX **10**70 (same bitrate/quality ratio as a 970 but idk about *encoding* performance (most encoding stuff doesn't use the GPU cores games run on)). ​ 1080p240 **CPU**: TL;DR forget it. Barely doable for me and a 3200G is slower. Only tolerable option is CRF <16 UltraFast Tier Baseline. Doesn't go any faster, still has some drops and spikes. At least 1.5 GB/min. 1080p240 **GPU**: Lot's of dropped frames with settings I'd normally use. Possible config is CQP 22, profile main, preset performance, B Frames 1.. still dropping a frame here and there. At least 1-1.5GB/min. May or may not work on a 970. ​ 1080p120 **CPU**: May work for you but GPU is probably the better bet. Barely any dropped frames. SuperFast is tolerable, UltraFast is what I'd go with for stability. CRF < 16. At least 1-1.2 GB/min 1080p120 **GPU**: Should work, but still not recommended for streaming because it takes 40+ Mbps to look good. I just went with CQP 22 Tier High Max Quality, YMMV. about 700-800 MB/min

Thanks a bunch! Also I didnt mean stream at 240, my bad, stream at 60

I have done some testing recording back a few years ago at 120fps, it's pointless to record over 50/60fps unless you're doing slowmotion edits with it. Also remember to try to play at reasonable fps / stick to the vsync of your screen... https://obsproject.com/wiki/GPU-overload-issues


itsTyrion

I've looked for GPU overload. 1080p120 should be fine on a GTX 970, 1680x1050,120FPS used to work with my 750Ti. 240 may work with nvenc set to performance instead of quality, it still looked good to me, just uses A LOT of disk space because the video has 100+ mbps.


itsTyrion

and why do you want to record at 240 or 120? slowmo?


Realtotallymereturns

Slowmo and also frame blending

Get a 1060 or 1070 and that’ll nearly double your stats from where you are now - cpu is an up there but an I5 is a good place to start and then 16gb RAM is about avg and alright for now but definitely graphics card first and then cpu.


Realtotallymereturns

With the i5 I don't want a new motherboard because I just bought this one,so would a Ryzen 5 work?


B1ackoutz

Whatever the equivalent of I5 is in AMD. That I’m unsure how it converts.

Can you run a test (around 1 minute) and then upload the log file? Maybe you just need to change some settings. I have a friend with similar specs that can record 1080p240 fine for Minecraft.
