I have now since upgraded to an EVGA GeForce GTX 960 4GB SSC GAMING ACX 2.0+ with this card I am running steady 60fps with no drops in framerates with most details turned all the way up, but now have a worse problem then drops in framerate.
Uninstalled all previous drivers for the 730 card and installed the latest drivers from EVGA. Now instead of frames dropping to 1 or 2 it now crashes to desktop. This crash has always happen after a long period of time firing the 8 inch guns. I have not had this happen while flying only using the large guns never in the other guns on the ships. When the program freezes it still shows 60fps at lockup with sound still running. This holds for about 5 seconds then CTD.
It reminded me of the OLD days when a game had a problem releasing memory and it ran out, and the machine locked up. But now at least you don’t get, the Blue Screen of Death.
The machine has 16 Gigs of DDR4 memory so if this is the problem, it would be like calling the hole in the Titanic a leak.
