A600 Vampire II Coffin Demo Slowdown.

Hi,

I am having a problem with the vampire 2 for my A600 that I'm not having with my vampire 4 standalone.
Some WHDLoad demos and games have slowdown.
I have V600 core 2.15.
My standalone runs the demos and games without slowdown.
Is there a way of forcing the vampire 2 to run in 68030 mode ?
I know if this is possible I wont have slowdown.
This is what I understand with WHDload.
I had a A1200 with a 68060 with the slowdown problem as well.
030 accelerators dont have the problem with WHDload.
Some help would be greatly appreciated.

Thanks

slowdown may depend on chipram access, but it's relative to some games and demos.
68060 accelerators for A1200 have problems with access to chip ram, this is well known.

Have you tried the turtle mode on your V600 ?

Yes and it doesnt make any difference, it needs to be in 030 mode.
 
  Thanks
 
68030 accelerators work well with WHDload

For example:

Deja Vu

With the vector part, about 2 min into the demo.

It doesn't happen with my V4 SA.

Also, last ninja 2 has slowdown

Thanks
