Hey all, as an owner of a 32:9 monitor setup (and possibly 48:9 in the future), I noticed that with NVENC, H.264 recordings would not run, forcing me to encode in HEVC, which NVENC on the 2070S is not capable of encoding in such high resolution.
Here's some information I've gathered so far:
NVENC H.264 - Maximum resolution supported - 4096x4096
NVENC HEVC - Maximum resolution supported - 8192x8192
Ryzen 7 3700X
Current resolution: 5120x1440 (2 1440p monitors); Planning to upgrade to 7680x1440 (3 1440p monitors)
