Windows desktop scaling

[PiBoSo]

If the Windows scaling is set to a value over 100% then World Racing Series will start at a lower resolution to compensate for the automatic scaling.

To solve the issue and use the full resolution: right-click on the World Racing Series icon -> Properties -> Compatibility

Then, on Windows 10:
Click on Change high DPI settings -> "Override high DPI scaling behavior. Scaling performed by:"
Select "Application"

On Windows 7/8 instead:
Click on "Disable display scaling on high DPI settings"
