Are you running the game in 64 bit?

Are your drivers correctly installed?

Can you try clean booting?

2) Type 'msconfig.' in the prompt and hit enter
3) When Msconfig opens select 'General'
4) Choose Selective Startup option.

Have you tired disabling Origin In Game?

Have you tried to repair NFSR in Origin?

Yes, already tried all my knowledge in this kind of problem and your advices.

The only thing I can't do is to remove ALL "pieces" left from Nvidia drivers + apps. I tried 2-3 driver-wiper programs + manual wiping from win and programs folders + registry

A 2-3 simple leftover items are unable to be deleted even with changed atributes to "full control" and safe mode windows runnin.

They shouldn't  interact with Catalyst driver but this is the only thing left to remove, thinking that the problem may be caused by drivers interaction 😕mileyfrustrated: 

 Thanq for your help and for your time! 😕mileyhappy:

Backdate your PC to before you installed the new drivers then try to download a different driver from AMD's site as it may be the driver.

Ok I found a solution that works for me for the moment.

Remember the fps unlock solution? ( -GameTime.MaxSimFps 60 -GameTime.ForceSimRate 60+)

For me works like this:  -GameTime.MaxSimFps 60 -GameTime.ForceSimRate 58+

It may be a driver problem from AMD but I say it again: my problem is ONLY on NFS Rivals. BF4 uses same game engine and runs perfect.

My solution gives a 2-3% unrealistic driving experience of course, but is not noticeable at high speeds.

You can try diferent values of course but keep in mind MaxSim needs to be higher than SimRate otherwise game wil run slow.
