F1RFT - Weird Graphics problem with all AI cars

[Ho3n3r]

Hi

I have a weird problem on this mod - all the cars not driven by me(bar 1 or 2 others, rarely) are massively scrambled - they are distorted and look like jagged objects as opposed to cars.

Does anyone know what might cause this, e.g. graphical settings or something else?

I have never seen this before on the 15 or so other mods I have previously installed.

Thanks for any advice
