It is very slow i was expected more speed. On Mame does that but on Demul? Why?

it's a bit slower than normal because of video recording software

I must say though that it and scud race look really nice with few(if any?) graphical glitches.

It's about what I'd expect speed-wise with h/w rasterization and an interpreter CPU running at the rated clock. Fortunately most of the Model 3 games are fairly light on the CPU and you can idle-skip or underclock the CPU to good effect.

actually, model3 emulation in demul is possible mostly because of Wind and DreamZZz (and mame/supermodel of course  )

Are they using an interpreter?
For Model 3, the two big bottlenecks are 1) the CPU and 2) emulating texture mapping (which poses some interesting challenges). Translucent polygons and dynamic meshes (polygon RAM -- some of which are quite large) will also have an effect.

And Model 1 and 2 can be emulated too?
If it's possible.
I Know we have Model 1 work on MAME and Model 2 Emulated now.
But a full collection of SEGA Will be nice
Hope i see Ollie King, Emergency Call Ambulance and Dirty Devils some day too 
My Dream will come true one day.

A MAME-style recompiler for the CPU rather than an interpreter should speed things up I would guess.

didn't model 3 have larger textures than say Naomi, sure they did.
But tecnhically it's a great achievement - what annoys me is all the lame people who will complain about speed/polygon correction etc..
People work for free FFS..

When audio is emulated there'll be a further hit
M3 can output 4 channels of audio as well (only a handful of games use all 4 channels, SR2/Daytona 2), and I guess when you emulate the MPEG board as well.
Still this will be faster than Hikaru emulation..

Its not really 'complaining', more like frustration, afterall, here we are in 2011 with CPU's that have upwards of 60 GFLOPS of calculating power, and yet cant run 15yr old hardware with CPU's more than 100 times less powerful.
Still, im sure speed will improve as they go.

Just because they're more powerfull doesn't mean emulation will be a breeze. It's like saying "Why doesn't my games paly full speed? They ran at 20Mhz, my PC runs at 2Ghz!"
