Hello to you too.
1. Read the stickies please and post all your systems details.
2. Check your temps and cool down your gpu or cpu if necessary.
3. Lower in-game settings. Most prefferably, monitor vram usage and see if that is the problem.
4. If you have good clean-installed drivers and all other demanding games work well, then it is not a general system stability issue but the specific game runs like sh!!t. Wait for new patch/ drivers.
