The problem is that you'll still have some upscaling artifacts whether at 960p or 900p.
I would even prefer native 720p with 4xMSAA than 960p + FXAA + upscaling.
Because FXAA vaseline is almost sure for this game I am afraid.
Anyway 960p is certainly a 16/9 resolution, not sure why the OP said it was 4/3. You can upscale any resolution you want to 1080p...The one pixel difference won't be noticed.
