Well I do.
I got it to run at 2720x1700. The game loses window focus beyond that (DEVICE_LOST blabla...)
Using retail 0.8 (alternate injection method) with forceBorderlessFullscreen set to true and tweaking the SplinterCell3.ini file (the one in C:\ProgramData\Ubisoft\Tom Clancy's Splinter Cell Chaos Theory)
Code:[WinDrv.WindowsClient] [B]WindowedViewportX=2720 WindowedViewportY=1700 FullscreenViewportX=2720 FullscreenViewportY=1700[/B]
(set it to Read-only after modification)
I'm still hoping to a get higher resolution than that as the game runs effortlessly (it's ooooold). I'll post updates tomorrow if it works
EDIT : nope I can't go higher. I give up. Hopefully someone will have more luck than me
Nice! I didn't think about trying to set the resolution through the ini, because the first time it didn't work.
I wonder if it'll work for Double Agent too.
