Description
On latest release of 8.05, the encoding performance seems to be halved (compared to 8.04).
I tested to transcode a H264 video to HEVC/AV1 with a RTX 4060 Ti (driver 576.52) on Windows 11. My parameter is
NVEncC64 -i input_video -c av1 --qvbr 34 --lookahead 32 --aq --aq-temporal --bref-mode middle --level auto --audio-copy -o output_video
With version 8.05 I get like
~270 fps, GPU 13%, VE 47%, VD 32%
either with HEVC or AV1 encoding. I remembered it's much faster the last time I used it, so I changed back to 8.04 and with exactly the same parameters, I immediately got
~510 fps, GPU 14%, VE 98%, VD 54%
FYI, RTX 4060 Ti has only one encoder rather than 2 so it cannot be a display problem mentioned in older issues.
Thanks for building the awesome tool and glad to help finding the cause of this problem!
