Crash Issues (GTX 760)

[Aborath]

Hey folks,

Lately P99 has been having issues. Playing in Windowed mode inevitably causes me to crash. This usually happens when I've been AFK for a period, but can also happen when zoning. If I play in full screen mode, suddenly AFKing works just fine, but I begin experiencing graphical issues (objects flickering, PCs disappearing, etc.). Has anyone had similar problems?

Specs are the as follows:

GTX 760 (2GB)
i5-760 OC'd @ 3.2MHz
160GB Samsung SSD
8GB DDR3 RAM
Windows 8.1 64-bit

The GPU and SSD are two more recent additions to my PC. Note that when I was running Project 1999 on a Windows 7, GTX 460, and HDD a year ago, the game ran just fine.

Project 1999 is being executed as an administrator, and in comparability mode (Windows 95).
