RDR2 is quite optimized. We spend a lot of time profiling before release, and while input latency can be a tad high, the rendering pipeline is absolutely highly optimized as exhibited by the large amount of benchmarks on the web.

This is why I love HN. You get devs from any software or hardware project you care to name showing up in the comments.

RDR2 ran beautifully on Linux for me. If you were part of the team, excellent work.
