I recently encountered a bug, let me explain.
When i updated TA Spring to versions b2/3 and Videocard drivers to 9x.xx and got a dual core CPU
The game ran really chunky @ 1680x1050 max (I have a 7900GT 256MB @ stock) when before it ran fine but the only difference been that i had later NVIDIA Drivers (93.81 Beta w/ Thread Optimization enabled) and a Opteron 170 @ stock w/ AMD DC Drivers and Their Optimizer program.
All i had to do (with the help of this Forum) was disabling Thread Optimization in my NVIDIA Control panel, does this mean this game is not Dual Core Optimized ? Also i hope this bug can be fixed, thankyou.
