EDIT: Fixed it by updating the radeon drivers to latest beta. I hadn't thought to earlier because 2D game. i have Timespinner on Steam and I cannot start the game. When I launch it, a blank white window appears (invisible when the windows classic theme is enabled). sometimes i hear what I presume is the logo jingle for about a second but sometimes it is silent. Either way the Windows "Timespinner has stopped working" dialog pops up after a moment and the program terminates. The issue is 100% reproducible. My hardware/software config is as follows: Windows 7 x64 2x monitors, 1 landscape 1600x1200, 1 portrait 1200x1600. The crash occurs regardless of whether either is set as primary Core i7-7700k Radeon r9 285 32gb ram I am happy to provide any further information I can to debug this.
