Looks nice from the video but once I enter the planet part it's completely unplayable slow. Even the space part is jerky.
Are you using shaders there?
nope, not at all...
what graphics card are you on?
i've run it on 3-4 PCs and haven't experienced this - even some mid-range laptops.
actually..... Windows 7 by any chance?
Windows 7 has lots of problems with OpenGL... do a google search for "windows 7 opengl" and there are countless threads. most seem to suggest getting the new nvidia drivers (such as this one)
http://www.overclock.net/windows/458892-windows-7-opengl-cs-1-6-a.htmlif you're ATI, then i don't know what to suggest... and if you're not running Win7, then I'm even more stumped...
Running XP pro with an NVidia GeForce FX 5500 (OpenGL drivers are likely the culprit). NVidia really did an ATI there and put out the worst drivers ever. I'm happy that it's mostly stable.
I wouldn't worry about that. On next opportunity I'll bury the card somewhere.
