My framerate starts fine and then after a bit it seems to drop. It just happened after I took my captain on a test flight, I redock and bam, my fps is halved.

Whats going on?

I have a GTX 1080

Turn off AA, glow and SSAO and you can max everything else out and get a flat 60 FPS at 3860 x 2140 in all but the most astoriod heavy area's.

If you play at a lower resoloution you can max everything on a 1080 at least I can. Glow really seams to eat frames the most.

It isn't about the framerate not being good, it's about performance degrading and then requiring a restart.

It seems to be a bug of some kind.

You can bet it is a bug/some sort of bad optimization. X4 just came out and since there was no public beta, the devs could not collect enough data to optimize the game. In the last patch (1.10) they even removed SSAA options.

I am sure though that this will be fixed in the near future. Egosoft is known for rough releases, but they actually work on their games and continue to develop patches and updates when they are needed.

Sounds like you run out of memory, either RAM or VRAM. Is that the 6GB version of the GTX 1060? How much RAM do you have? Which OS and do you keep any RAM hogging programs on in the background?

OOPS! I misread the GPU, sorry.

Frame rate + suddenly halved often equals a vsync problem-- which they have admitted to having with NV hardware. It cannot sync at 144 or 120 or 60, so it is probably doing 30. It is my understanding that dynamic sync rates on NV hardware are not currently working.

^ ^ ^
This sounds more plausible than my suggestion.

Let's hope it's a vsync issue, and it's a 1080 not a 1060, it has 6gb I believe.

I have adaptive vsync on, and the framerate is fluctuating, if the vsync function is at fault, it's creating some crazy behavior, it's not operating like vsync, it's not doing those perfect whole numbers.

edit: I did a couple of things in the Nvidia control panel to help:

1) I set my refresh rate to highest available

2)I set my vsync setting to adaptive

It still happens though
