Some things I'd like to see
-Instead of pressing Jump to start a match or respawn, I feel it would be a lot more streamlined if you press Fire instead, or at least have the ability to do so.
-I would love to see a way to disable showing you the scoreboard when you die in DM, because I hate knowing my rank. It makes me anxious. In addition, I'd like a way to disable the new scoring display on the bottom left of the new HUD.
-A bug, when you go to disable auto weapon switching in the middle of a game, the setting won't apply until you hit the apply now button on your player settings.
-The water. There is no getting around the fact that it is fugly in Nexuiz. This can be easily evaded by the use of realtime reflections, such as are in the map Ruiner. But, even on my GTX280, they have a SEVERE performance hit, even when you set the reflection quality to the lowest setting, my FPS will dip into the 20s and 30s. An alternative to realtime reflections would be cubemaps, such as are used in Unreal Engine 2. Also Half Life 2 seems to do realtime reflections without much performance hit.
-It would be cool for there to be special effects like motion blur, soft shadows, heat and particle distortion, etc...
-A big one. There should be a way to cap the framerate. It fluctuates widely and can be a hindrance.
-Please don't nerf the Crylink, it's my favorite weapon

-In fast paced games, it can be tough to tell what weapon you just picked up. It would be great if when you pick up a weapon you don't already have, the weapon name could be briefly displayed in the middle of the screen, and not on the death log where it is instantly pushed away by death messages.
