Well i've only had a bit of time on it over the weekend, but I've had a right mare.
Firstly, on Friday it keeps crashing "The Division has stopped working". I didn't have any issues on the closed beta. Ran it for an hour last night and it didn't happen again.
Secondly, I upgraded to 21:9 last week, I've ran it on 3440x1440p Ultra, with V-Sync off. I'm getting around 27fps avg on Sli 970s that have been clocked to be slightly better than a stock 980ti. Now I'm praying to RNGeezus, that this is just an optimisation issue, as the latest Nvidia drivers gave us the Sli profile for Division. So my heads a bit blagged at the mo.
