Problem texture pixel asphalt custom tracks

[kimi81]

Hi everyone, I have a problem with Assettocorsa when I play with the custom tracks I find that the asphalt in front of me is all pixelated and of low resolution as I get closer the resolution becomes good. With the original tracks by Kunos this problem is not there. look at the photo

I solved.

Motion blur must be set to off
