Any reason why you're running smooth motion on for the Division 2 whilst using a 4090? Surely you're getting enough FPS at native to not even consider needing smooth motion!It's always worth updating. If the current driver works fine and the new one has issues, you can always install the old one over the top.
They may have fixed or improved things that weren't in the patch notes. The Division 2 runs much better for me with smooth motion on in the current driver compared to the last official release, and that fix certainly wasn't listed.
