#Toaster 3.1

I recently purchased the Toaster 2.0 to 3.1 upgrade software, hoping to get the quoted 10x increase in Lightwave speed. After rendering a scene which I had used in 2.0, I noticed that it took about the same amount of time. Am I doing something wrong, or does the increase only apply to certain operations ? Thanks.

What type of h/w are you running LW on ? On my 2000/040 system I increased about 2x between 2.0 and 3.0 s/w if I remmember correctly. ….John

try using alot of antialiasing.. there are great speed increases there.

Jim, It is only really noticable on '040s and where there are lots of maps. I have one Toaster on an 030 and one on an 040. Before the 3.0/3.1 updates the '040 only gave about 20% better perfomance sometimes and sometimes was slower. Since the update the difference ranges from 3x to 5x depending on the scene. I have OCCASIONALLY seen 10x, but I'd say on average it is about half that. wmc – via Autopilot!

Thanks, Wayne. I have an '040, and the 2.0 scene I tried with 3.1 had some bump maps, image maps, and refractions. It took about the same time as in 2.0. It may be the antialiasing and other extras that 2.0 didn't have. Thanks.

Jim, You have MoveSSP specified? Makes a big difference. The sequence (assuming yo have a GVP board) is: ;BEGIN 68040_FastROM cpu nocache noburst nocopyback ; suggested by Mike GVP 5/10/93 SYS:Utilities/GVPCpuCtrl MoveSSP FASTROM cpu cache burst copyback ; suggested by Mike GVP 5/10/93 ;END 68040_FastROM Without the moveSSP, it is about the same as a '030. wmc – via Autopilot!

Is there a way to get a similar MoveSSP speedup with a PPI 68040 accelerator in an Amiga 3000? I inherited this machine and it came sans documentation…. Thanks. — David Schachter

I don't know PPI hardware. The MoveSSP I currently use is an option from the GVPCPUctrl command. However, I remember a PD command of that nature that worked with any CPU under 1.3. I haven't been able to locate a generic MoveSSP for 2.0 and have no idea if it would be as much of a boon as the GVP supplied one. wmc – via Autopilot!
