[sldev] Havok4 Public Beta is here!

[SL - Farallon Greyskin]

Well I tested out a bowling alley I made some time ago but could never sell 
because 1 in 20-30 times you hit a lot of pins it would crash the sim.

I never got the sim to crash but...

The physics engine seems to be /at least/ twice as slow as the current one 
according to the numbers. 11 objects interacting in a tight space for a 
couple of seconds sends the the entire sim into time dilation down to 0.5, 
physics engine to 25 fps and a physics frame time of up to 32ms! That is a 
huge hit. Testing on my private sim the hits are not nearly as severe.

Beyond that, the physics are much MUCH more sluggish.Especially when 
dragging the ball around. The beta /feels/ like it is actually like 5 or 10 
times slower when hand moving stuff using grab...

Is there a chance that it is running in like a debug mode or logging mode 
that is slowing it down? Or is this a by product of the abstraction layer? 
Or is this running full speed? (Sim was empty and everything was running 
full speed during my testing, lag only hit when I bowled)

Besides being more secure I was /really/ hoping that Havok 4 would be like 5 
times as efficient as havok 1...

I will post findings on the beta site...
