From playing up until the second hub, I've encountered rare cases of "audio scratch" (beginning with characters in the second hub), slow down / speed up, and two crashes during the first real boss. While these problems have been annoying, this game is still worth playing and is perfectly playable - just not quite the perfect compatibility I would like to see. On that note, if you look at the System Requirements more closely, it specifically states:
"Minimum system requirements: Windows XP / Vista / 7 / 8, 1.8 GHz Processor, 512MB RAM (1 GB recommended), 3D graphics card equipped with 2048MB Video RAM or less, compatible with DirectX 7 (compatible with DirectX 9 recommended), 2GB HDD, Mouse, Keyboard. Compatibility notice: This game is incompatible with graphics cards equipped with more than 2GB (2048MB) of Video RAM."
If you'll notice, this game requires a PC with less than 2GB video RAM in your graphics card and is recommended for DirectX9 - that means that if the video RAM in your graphics card is even a little over 2GB like mine (at about 2.4GB) and are using the newest version of DirectX like I am, you'll run into some more problems. I really hope that GOG.com is able to improve this though, as I'd really like to be able to play this game on a better computer in the future.
EDIT: This message was pre-patch - now that the patch has been released and the gamepage has taken notice of this, this post is no longer relevant. Everything is fixed with the patch!
