It's disappointing. I was interested in this game, thought it looked a bit original, but being basically an Unreal mod I knew there was pretty much no chance of it being anything but vert- and so didn't buy it. Shame!
Actually, it's a tiny bit better than that...
5:4, 4:3, 16:10 and 16:9 are the only aspect ratios natively supported, and the default FOV is 90 in 4:3 BUT the game has some crude widescreen toggle that
natively applies FOV 100 to both 16:10 and 16:9.
I will post a Confirmed Solution with screenshots soon, and maybe a full-fledged DR later but here's a teaser.
According to FOVCalc, 16:10 requires FOV 100.6 to be Hor+. 100 is close enough. The Ball is natively Hor+ in 16:10 !
It's a bit loo low for 16:9 though, but a simple .ini edit can fix that.
Unfortunately the maximum FOV value that the game will register is 120. That's not nearly enough for 15:4 TH, not to mention Eyefinity.
Whoever is responsible for this particular handling of widescreen resolutions (Teotl or Epic ?), I hope they'll continue their effort in that direction - the limited FOV and Vert- weapons are the only obstacles to satisfying multi-mon support in The Ball and so many other UE3/UDK games...
