Joined a multi-plyr mission starting in a dark pit at night for ramp start. After multiple attempts at rejoining, the same occurred each time--pit would disappear and a blue horizontal streak which seemed to be the horizon appeared. This would happen when looking up from the pit to the sky.
On other occasions while flying in multi-play I'd loose the aircraft graphics, still had sound. It appeared that I was still flying over water in midair without an a/c.
It was suggested that I needed an NVIDIA dvrs update (GeForce GTX 260 & AMD Phenom II x4 965 processor, 4 Gb of RAM), but the update yielded no change in the issues as described above.
Most of the in-game graphics tuned to medium except Textures still high.
Any ideas other than a new vid card?
Thx!
