Question / Help High quality local recording / aliasing issues

I know there's a FAQ for this. And I've read as many guides as I can and yet it still doesn't make sense.

Compare the left and right images. Both are from Deus Ex using the same graphical settings.

The left is a screenshot using print screen. The right is from a Open Broadcast Software video.

Notice the blurring of the edges, and the artifacting around the van.

I keep upping the video quality, even with CBR, and it the capture always feels "wrong." That last picture is from a bitrate set at 20MB/s.

- Encoder is x264

- VBR looks terrible. It'll never take more than a 1-2 MB/s of bandwidth regardless of quality setting, for 1080p.

- CBR looks way better. (Which is strange because all the guides tell me to use VBR.) VBR was horrific for Jagged Alliance 2.

- I'm running veryfast CPU preset. I've tried slower but I don't recall huge improvements.

- High encoding profile. (Default)

- Uses "CFR", full range, key frame = auto/0. (Defaults)

- No resolution downscaling, running in 1080p.

- GeForce GTX 560 SE + AMD FX 8370 with NO loading problems. Video outputs to an SSD.

I think this would all be fine for a Twitch stream, but I don't want Twitch-mode. I want "FRAPs" mode.

---------------------------------

What should I be doing? Where should I be looking? As far as I can tell, there are no more exotic h264 tweaks exposed in the GUI. (Except trying a higher CPU preset?)

Thanks in advance.
 
First, not an apples to apples comparison. Do the same image for each.

Second, its probably the same aliasing that appears in-game. With that old GPU, I can't imagine its doing any advanced anti-aliasing.

Third, if it was an encoder problem, the "poor quality" would appear in the form of compression artifacts, not bad aliasing.

Fourth, follow this guide for recording to disk: https://obsproject.com/forum/resources/obs-classic-how-to-make-high-quality-local-recordings.16
