What is the model of GPU you have? I know you have put NVidia but trying to get an idea on the age/ performance.
If it can run other games fine (such as PUBG) and solely only has the issue on this game, its very odd. Could you confirm the following settings for me:
1. Open Nvidia App
2. Click on the 'Graphics' tab
3. Check if you use the 'Program Settings' for the specific game?
Note: I would highly recommend having this part not used and disable/ not optimize in here. This has for myself been an issue for specific games and when turned off and just managed within the game then win win.
If the following looks fine above, I would then try the following test:
1. Open 'Device Manager' within Windows
2. Expand 'Display Adapters' (You should see both the AMD & NVIDIA GPU)
3. Right Click & disable the AMD one (as you will always use the NVIDIA one anyway)
4. Boot the game and test
Yes for the first 3 steps i try it. And its the same only windowed and use integrated card. For the following test i try this 4 steps and when i desable integrated card, the game start full screen and used nvidia card but performance become bad, heavy stuttering even in the main menu.
