I've a gtx 960 witch is normaly a little less powerful, and even with a little more graphic options, I don't have these problems. (Note than I don't use 737 but a320neo jardesign).
For readon do you have an app to optimize you game performances/3D parameters?
The update is gon'a be payware... I'm an owner of the V3 and I'm a young student so that's not cool. It's pretty hard to change my pc so if I've to pay 20$ more it's not easy... 5€ or 8€ will be more reasonable.
Thanks for understanding
