Cheat Engine

[ENUMBRE]

Hello, Cheat Engine forum folk. Today I've been trying to figure out the best way to record 240FPS gameplay footage. I have a 240hz monitor and it's nice to have 240FPS game demos to review. It's also fun to make 240hz webms. For those with 120hz+ monitors they look very cool. I would link one, but this forum doesn't let new accounts post links.

Anyway, I did some Googling, found lots of other people with this desire. Didn't get any help. OBS can record 120 FPS gameplay footage (and with NVENC, for lower CPU usage!), but that's only half of 240, you see.

On a lark I decided to memory edit OBS's framerate input field (which normally only lets you put in values up to 120) using Cheat Engine, and surprisingly enough it did work. For posterity who may be viewing this thread after Googling 'record gameplay 240 fps', you only have to edit the input number from whatever you have it at currently to 240, freeze it, and press enter in OBS. OBS does flawless 240 FPS NVENC recordings once you do that. And it remains at 240 until you change it, so you don't have to fuck around with Cheat Engine each time you start up OBS.

Here's the dilemma. Even using NVENC encoding, OBS uses a decent amount of CPU to record at even 60 FPS. 2.4% of my 5ghz overclocked 7700k. If I record at 120 FPS it's double that, or about 5%. If I record at 240 FPS it takes up a significant ~10% of my 7700k.

10% of my CPU happens to be enough that I dip below 240 FPS in Overwatch teamfights. Overwatch is a CPU hog, there are only a handful of CPUs which can get 240+ FPS in it.

SO!

Shadowplay has really low CPU usage. At 60FPS it uses 0.2% of my precious precious CPU. A whole lot less than OBS.
I need to know if Shadowplay can be edited to record at 240 FPS in the same way OBS can. I've been trying for an hour or so, but if it's possible it's beyond my extremely basic understanding of Cheat engine. Any cheat engineers with NVIDIA cards able to help me out?
