hi when i play the game the light of the car are square. check those screen shot

 

my spect:
-nvidia geforce gtx 650 1g ddr5
-intel core 2 duo cpu E8400
- 8 g of ram

i know that my spec are unther the recommandation to run the game but there was no problem befor this.

for the mod, i have car, map and the mod of cessni.

 

The mod is known to do that when you're on Lowest graphics settings. I recommend you switch to Custom graphic settings, keep everything except texture quality on Lowest, with Texture Quality is set on Normal.

 

thanks it work
