Yes the table stutters a little bit on my computer as well when all the lights are flashing in the same time +
DMD animation (like when you get extra-ball, Jackpot etc...). I have some ideas to optimize the script, I will try them on the next beta, hopefully the problem will be reduced or fixed...
Any ETA on a possible release date?
I can't say precisely because every time I think that something will take 1 week, it finally takes 2...
On the videos, the version running is the beta 0.42 but I'm already working on the v0.5. the v0.5 and v0.6 will be the 2 last big updates, everything else will be much faster to do.
So I don't know when the table will be 100% done, but I really want to finish it before 2012

Here is the to do list:
- Beta v0.5
With the 3 Flashers close to the skull, the skull eyes, the skull target and the 3 last lights (Timer, Jackpot and ExtraBall).
Left bumper animation.
- Beta v0.6
The last flasher under the plastic ramp (This one will be complicated)
The 2 last bumpers...
3 red Targets in the center of the playfield
- Beta v0.7
All the sounds... I will probably change all of them
Ball texture animated -> I don't think that I will play to much with that because I'm not sure that the effect will look good.
- Beta v0.8
New flippers gameplay (flipper pass, drop catch, live catch etc...)
- Beta 0.8 --> 1.0
Gameplay pass with BFG_Brutal and Gear323
