Hello,
Might be an issue with SLI mode / dual GPUs, in the game options there is a setting to enable which may help.
If you used Steam go to where the game is installed. X = your drive letter.
X:\Steam\steamapps\common\APB Reloaded\APBGame\Config
Edit the APBMachineOption file.
Look for this line ;MultiGPUCompatibility=False
delete the ;
and change it to True.
MultiGPUCompatibility=True
Save the file and see what happens.
