GTR2 Running poorly on new gaming rig

[Madatek]

Specs:
AMD Sapphire RX 560 4GB (GPU/Mem clock @ 1300/1750)
8 GB Ram, DDR3
AMD FX 6350, 6 Cores @3.9 GHZ
Tried to use the 4gb patch, also the Set Affinity system

UPDATE: So the problem also applies to rFactor. Also, while the GPU usage is around 100%, the VRAM usage is at like 0.5 GB Ram. Kinda weird, isn't it?
Also CPU usage is extremely low at all cores.

download the programm "process hacker". it is a taskmanager with some useful additional features.
if you open this programm and gtr2.exe already runs you will find it as a task, right klick on this task and
chose
1. affinity -> assign all cores
2. priority -> set above normal
3. i/o priority -> set high (admin rights necessary)
and you should encounter a nice speed boost.

Search for 4gb patch for GTR2 and Process Lasso program. They are absolute must have if you want to play GTR2 on max settings. The first one allows the game to utilize more RAM while the other one enables multi core usage. When using both the improvement is huge.
