I've tried playing Eufloria and then Dyson on my new laptop, which has an ATI MOBILITY RADEON 4570 (my comp is a Satellite L350 21U by Toshiba).
The games runs, but is very slow (read: unplayable, like less than 2fps) but the sound seems to work ok. I have to click at least 2 or 3 times to activate one button on the main menu. In the option screen I can't see any of the text, everything is white but the scroll bars.
I have attached a screenshot of the main menu and option menu.
Specs: WinXP Pro SP3, Core 2 Duo 2.10Ghz, 3Gb RAM, ATI Mobility Radeon HD 4570 1Gb with drivers that can run Left4Dead and TeamFortress2 (drivers date: 01/12/2008). So I'm guessing it's having a problem with the graphics engine (which is openGL or something, right?). Also nothing else is running in the background, I'm very picky about what runs on my computer.
