Changing the video quality option doesn't seem to do anything at least for QSV/NVENC MP4 recordings, lowering the bitrate slider does indeed lower the bitrate (except I'd like to go higher not lower).
Is there a chance the bitrate values could be raised (maybe setting the new default to the previous max bitrate), or better yet letting us set the average/max bitrate settings like most other game recorders allow? I've had near perfect quality recordings with other programs using higher bitrates (50Mbps+) with NVENC, including Shadowplay.
I bought Action because the near lossless AVI codec works excellent at 1080p60 vs all other options I've tried with other programs (Lagarith/UTVideo/MagicYUV), but NVENC/QSV would be great for those times when I don't need a pristine copy and want to save some space (but the quality IMO is too low to do so).
The example below is one of the least problematic (though still visibly different), trying to record Skyrim SE just turns the grass/vegetation all around you while riding down the road into mush.
