Turn down your draw distance if you lag.
It's SEVERE lag, lowering the draw distance does very little, and it's extremely difficult to dogfight with a lowered draw distance. The islands don't need to look pretty, take note from LegoPepper's extremely successful dogfight, he just has a bunch of low in brickcount islands scattered around. You 2 giant islands in the middle with two ships next to it, there's very little to navigate, it's laggy, and it looks silly.
I know my computer's stuff, but I still know some people who experience the drop in FPS like I do. Not everyone's running on a dream machine, and that's what I fear someone needs to run this.
Someone earlier argued that it was for the intent of restoring how the original looked, but in reality you've changed almost all of the weapons, so clearly that isn't your intent.
This should sound more pissy than anything, don't want to sound offensive, Greek. Love what you do, but I just think there's a whole bunch of mistakes going on here, and it's making it infuriating. Very rarely do I completely refuse to play in a DM from lag, especially when it's a dogfight, but this is an exception. Between the weapons, the build setup, and the FPS drop, I see virtually no benefit other than the server running stuntplanes.
