DSR vs MSAA?
DSR vs MSAA?
I started Metro Last Light Redux a few weeks ago, powered on 4xAA from the beginning, but was let down by poor framerates. After reviewing the settings again, I realized it used SSAA instead of MSAA and that explained the issue. I didn’t remember this until your comment highlighted how tough AA was for that card.
This simply indicates you overlooked studying DSR and DSR Smoothing.
