Vehicles jitter and become choppy in Bot Gameplay
We have a bunch of vehicles in our game. When you test out one of our maps and play alone, you can fly/drive around in our vehicles smoothly and they behave physically as expected. However, when I add bots (especially when I add a lot of bots like, let's say 30) vehicle movement becomes VERY choppy... It just feels plain bad.
I tried the same thing with a clean UDK install and an empty map. Same thing... so it's not like we screw up with something, but seems to be a problem built into UDK itself. It becomes best visible with flying vehicles, like the Cicada. Simply spawn it in an empty map, add a lot of bots and try to fly around with it. It simply doesn't work, i.e. doesn't feel right at all.
Any idea what needs to be done to fix this? :idea:

- the bots use the same mesh you do I believe.....if you get the bots to use a simpler version that might help.
- if your using a lot of collision meshes they should be as low as possible, 30 players moving collision meshes of 4000 polygons will simultaneously calculate a total of 120000 polygons, try getting high framerates with that.
instead go for superlow collision meshes so that the server dont need to calculate so much. when i modded a collision mesh should be sub 200 poly. - We had a similar problem in our vehicle game but it was down to frame rate. I believe because the computer is trying to run so many computations per second that it breaks the physics for the vehicles. Run fraps in the corner and check your frame rate, turn off any post processing or remove bots from the game until it runs stable. (not a programmer)
