mihe8: I'm sick of this. Almost every so-called classic game purchased via gog has massive issues, is not optimized for modern resolutions, widescreen etc. INI-tweaking all day long. That's that. Cash-in for no invested work. Fine.
But now Sanitarium is like the 3rd or 4th game (Escape from Monkey Island being the one before that) I purchased that just wont even start/has black screen on start with NO goddamn possibility to alt-tab out of it. Leaving me to restart my computer. You Serious? Dont fuck with my hardware. In fact get the hell out of your lazy asses and test this shit before SELLING it.
What the hell are you doing with these games and how in the world you even think you are in the position to want my money for this fucking mess?
Best is to run Escape from MI in the newest ScummVM engine (which is now merged with ResidualVM, that was the previous way to go).
It
is possible to get it to run natively (use dgVoodoo), but it's just a PITA.
Sanitarium: Make sure you install the latest version (5xxxx) and not the outdated one (2xxxx). That one already runs in ScummVM and has no problems at all.
If at all, you might have to change the render method, if your graphics card does not support the one selected.
That happened to me some time ago. Until that driver version, everything was peachy, but then I had to change the method used for DOSBox (ScummVM is fine), which was set to Overlay at the time.
If you ever face black screen problems:
Instead of restarting your computer, press Ctrl+Alt+Del, then Alt+T. That opens the task manager. If you still see nothing and are using Windows 10, then type monkey, followed by Alt+T. The Windows 11 task manager is not as convenient for blinded keyboard users. But if the list of games has the focus when it opens, you can also type the application name, then press the context menu key on your keyboard followed by [P].
What sometimes also helps, is locking your PC by typing Win+L
I was told that switching desktops by pressing Win+Tab (and then opening a new one) also helps.
The 3D games from the late 90s and early 2000s are the worst. Getting them to run on modern machines is work on academic levels.
GOG can't see into the future. They don't know how drivers (or Windows) will change. If you want to play old games, you always have to be ready to do some handywork.
In my opinion it's best, if you have ONE installation of ScummvM and add all your games to it. This way you only have to do your system settings once and only have to change very few things depending on the game (MIDI/Adlib or find the coolest looking interpolation mode for each game).
