The original Deus Ex has a res limit of 1920x480 on the TH2G as it is a Dx 7 game ... :(
There is a limitation of DX7 and below on framebuffer resolution to 2048 which is why you can't get any higher ... :(
Damn . Thanks for saving me headache though.
Also cheers Ibrin. I will still give it a go but at a lower resolution or something. I wonder if 2048 x 1600 will work? At least soem of the border will goaway. Although I really wanted a widescreen resoltion . It's so strange to play in 4:3 after playing with widescreen even if it is a huge resolution like 2048x1536.
I just realised that my post has become a thread. Thanks to whomever did that. I appreciate it .
