Question / Help Artifacts when recording with nvenc_hevc

[TheDuckTeam]

When recording with nvenc_hevc I have noticed that the video has artifacts in it and it's really bad. Is there a way to fix this? I record at 240fps because I want the gameplay to be much smoother, could this be causing problems? Also, I use FFmpeg for custom output

EDIT: This is not a troll, I am completely serious. 240fps clips converted to 60fps look much better than the clip being 60fps from the start. My specs are:
i7 8700k
Gtx 1080
16gb ddr4 @3200mhz

Your system is unlikely to be able to encode HEVC at 240 FPS. Reduce the resolution or frame rate.

I record at 240fps because I want the gameplay to be extra smooth

I don't know who started this, but this troll is quite successfull in the minecraft community, change it to 60 fps.

Actually this is not for minecraft.

A long time has passed but I was wondering if an i7 8700k and Gtx 1080 are not powerful enough for 240fps in h265
