Hello, fellow GOG users

I've just bought Sanitarium and would never be able to stand playing it at a horribly stretched resolution, widescreen or not. It's one of those titles you simply have to play in a window. I came across a topic and found that the command-line switch -window exists. Unfortunately for me, it also causes very painful slowdown which seems to become much worse if I enlarge the window.

I'm on Windows 7 x86 with all updates installed and I keep my system well-groomed. Possibly relevant specifications, if you really feel they're required, are as follows:

Gigabyte 945P-DS3
Intel Core2Duo E6600 at stock speeds
ATI Radeon 4950
M-Audio Delta 1010LT

Has anybody else encountered this problem? Does anybody have a solution? I'll continue mucking about and see if I can solve it.

Tried disabling visual themes and desktop composition in compatibility options?

I should have mentioned in the first post that I did try those things; I tried every compatibility option available as well as some other stuff which can often help stubborn games run correctly.

Hmm its puzzling why its lagging in windowed mode, does it also do the same fullscreen? If not if you set it back to fullscreen and go to your ati control panel I believe you should beable to set scaling with fixed aspect ratio on that and force it on your game.

Indeed. I've always known I could do that, I just wanted to try and find an alternative solution because a stretched 600x480 resolution, even in its correct aspect ratio, is quite ugly. Thanks for your contributions, Ralackk.

Well I'm not 100% sure with a radeon card, not used one in a while now but with nvidia you can force not to scale. So it would have the 640x480 resolution but have black boarders around it. Should be the same effect as windowing it minus seeing your desktop and being able to do other things.
