it's fixed, thanks for helping me!The newer mods and some of the newer tracks drop your frame rate, as for the sound you may have to uninstall and reinstall.
It is really important to tell us what mods and tracks are doing this, if you're running the MECS '17, '18 and '19 you're going to get frame rate hits because the car files are huge. Some tracks like Daytona TE have graphic issues that the maker needs to fix.
i've used the NR2003 graphics tweaker and it's fixed nowWhat was the fix?
