Consider this the request post.
Right now, there are two items that I see as being needed for Terraria v1.3.5.x.
1) The ability to revert to the XNA Reach profile. People who have older (e.g. crap) machines/GPUs don't appear to be able to run the game anymore. When I look at the resolution code in Terraria, they appear to still have the old non-4K limits in place if the Reach profile is embedded in the executable. I already have the code to handle this.
2) "Uncap" the minimum zoom level. This is going to take a little while to figure out where they're putting the cap in place and then figure out how to circumvent the cap. (Update 4/21, 8:00pm: I just started up 220.127.116.11 and...yeah, rather than scale to pixel, they're scaling to their "maximum" 1920x1200 view. This might take a while to figure out.)
Anything I'm missing?
