Copy GTR2 Steam folder outside Steam and make it a standalone version
You don't need the patch all that is included in Steam already
You just need a 4GB patched NO-CD ( running the 4GB patch can give extra stability )
There is debate which version has more flicker but that may be dependent on hardware, drivers and 3rd party content
Before you add anything to the new standalone test it then back it up as is
Anytime you want a fresh or second GTR2 folder copy it anywhere and make a new shortcut
Set both GTR2 and GTR2config permissions and compatibility for
all users
Set Admin, Set Windows 7 compatibility mode
I know everyone says use XP mode but then it will set only 512mb of memory
When GTR2 only sees 512mb or 1GB it will set a lower OBJLEVEL and TEXDETAIL
and you will see warning levels in graphics details sliders ...............just annoying, no biggie
After I run config I set :
CPURATING=5
SYSTEMRAM=
4096
VIDEORAM=
4096
OBJDETAIL=
1
TEXDETAIL=
1
VIDEOGUID=D7B71E3E-58C1-11CF-7555-0F131BC2DA35
If you set BOLD you will see no pesky red warning levels on sliders
If you run nvidia use Nvidia Inspector to set AA levels
Here is my profile with that you should see super smooth models in spinner

Open screenshot to 100% size ( 4K ) you should not be able to find a single jag and less then any modern sim !
CLiCK on "view image" and set 100% ( you have to lower more then 100% then raise back to 100% )
