I can confirm that there's only 1 screen in my PC.Can you confirm you're on one single screen and don't use a second monitor at the same time ?
Using the keyboard or anything that might give the impression you're on another window or software than GTR2 might create the same result as using Alt-Tab .... with another original GTR2 than the Steam one.
I'm always letting my GTR2 runs on Normal Priority and setting max cpu cores to more than 2 cores, but it still crashing...And is not a Game's CTD or causing the whole Windows BSoD'd, but it will freeze the game(No matter what's sessions when the games on, even in Menu) and need to Ctrl+Alt+Delete to making it stop.Perhaps you have changed gtr2.exe program priority to high or idle : it is not a good idea as it can freeze your computer, always let it on normal.
The only setting to change is affinity with max cpu cores or at least 2 cores.
I Tried it, but still useless.One thing to try is running in window mode.
Can use this program to make it border less.
-Both GTR2Config and GTR2 is using admin setting with XP SP2 compatible mode.- And I suppose you're starting GTR2 with admin rights and same for GTR2config also .... and in compatibility mode ?
- Is your GTR2 an original older version or Steam version ?
- if original version, where is it installed ? main disk ? in which folder ?
Answering those little questions might already confirm us that your problem is not first of all a GTR2 install or use problem.
What I feel strange in your case is .... that any click or keystroke may freeze your GTR2 .....
Normally, as long as you click something or use keyboard inside GTR2 for GTR2 itself .... it shouldn't freeze at all.
Now using special keys to launch any other software should also surely freeze GTR2 as the focus should be surely given to the new started software.
NB: My PC is also rather new with MSI RTX 2070 Super Trio - I7 9700k and 16 GB Ram and Win10 64bit of course.
No problem with either original or Steam GTR2 versions. Both ( even 3 installs ) are installed outside C drive and none inside Program or Programfiles (x86) folder.
I have DX9 installed. And ofc I choosed "Direcx 9" instead of Auto.As he can drive Assetto Corsa without any problem I really don't think it's a real PC component problem. A problem should have already happened with it too.
As I still can understand..... GTR2 is not really crashing .... it's hanging for good: nothing can make it move and it cannot be closen else than with the task manager.
That's why I think more of a software problem than a hardware one.
The last question I forgot: for the DX9 ... that's well the one you choose in the GTR2 config and not the "auto" one ... ? ( in fact I never tried this setting ).
But yes ... do you have DX9 installed ?
And something else as we don't know where you live: US or EU Patch 188.8.131.52 ? ... I don't know what can happen if it's not the right one.
I tried to using alternate video drivers, but nothing special.Perhaps MSI disabled dx9 support by default in your all new videocard ???
For sure you can try alternate video drivers.
You can also check BIOS version of motherboard/gpu : maybe some updates have fixed this issue ???
Maybe a wrong setting in motherboard bios : try a reset to stock ???
if your pc is brand new then you've got possibly a faulty composant (tiny transistor somewhere) : as Shovas said, did you try demos to stress your composants ? In general it could be cpu, gpu, motherboard or ram : if it is new then you can ask for a replacement or refund but you should know which one ???
