Already did a steam integ but to no avail, any hint on how to fix a error loading mesh into memory ? oficial le mans and oficial porsche rsr. thanks
Well only tried this track, system specs is a i9 9900K @ 5Ghz, 16 Gb of RAM DDR4 3200 and a 2080Ti...
Did you join a server that used that mod or do you have a non S397 update installed? On your screenshot is Version 2.0 of the car shown. I have version 1.98 and 1.99 installed and get no official 2.0 update downloaded. So i would say that the problem is caused by the 2.0 update. Check your inventory and uninstall/delete the rfmod or rfcmp with the 2.0 update of the RSR.
Check the folder ..\Steam\steamapps\common\rFactor 2\Installed\Vehicles\Porsche_991RSR_GTE_2017 there should be only 2 subfolders inside, 1.98 and 1.99. If there is a folder 2.0, delete it. And in game use "All Tracks & Cars" as series. It should load properly then.
