Hi, just installed and when I try to start the game I get an error message that reads:

Assertion failed: RenDev [File:WinViewport.cpp] [Line: 787]

History: UWindowsViewport::OpenWindow <- UGameEngine::Init <- InitEngine

Any Ideas? I'm running W7 Ultimate 32Bit

Same thing here but running Win7 Ult 64bit. I keep getting the error
Assertion failed: RenDev [File:WinViewport.cpp] [Line: 787] History: UWindowsViewport::OpenWindow <- UGameEngine::Init <- InitEngine
I've set it to win xp SP2 compatibility and everything but still no dice. This is the second game i've purchased from GoG that i cant seem to get running.

According to the error message apparently it's an issue addressed to the graphics. Sadly it doesn't tell the exact trouble maker. It could be caused by quite many things: from not appropriate display settings up to a graphics card which is simply not supported.

Would need some time on trial and error, if you really want to get it to work.

Kind Regards

Same here.

Win10, nvidia nvs 310

@NeuroticAnarchy

Have you tried setting ReduceMouseLag=False in System\XIII.ini?

It helped once for booting issues.

Have tried that. Still the same issue.

Have you already been over there? https://pcgamingwiki.com/wiki/XIII

If nothing helps for now, you can switch to window mode and resize it to fullscreen-like dimensions.

All right windowed was the way to go for me

Thanks..
