I probably wouldn't mess with process priority by the multithreading option is interesting. I wonder if this will take advantage of a Quad Core?

Just gave it a try and I got about a 5% increase on Blitz.

My understanding is that the -mt command creates an additional thread that handles the final outputs. Any mutlicore CPU will gain something from this switch, but it depends on the CPU speed and the ROM being emulated as to how much you gain. It doesn't effect the software SLI feature of MAME used to emulate 3DFX hardware and alike, this feature work regardless of the -mt switch.

I had someone on another forum run a MAME benchmark on his Core 2 Quad Q9450 which is overclocked to 4ghz, on Vista 64bit, running MAMEUI64 it benchmarked Gradius4 at 126.75% where as my Core 2 Duo E8500 @ 4ghz gets 119.7% running the same setup, so while the gain on a quadcore it's not really worth the extra cost of the CPU.

So I got my new computer put together which consists of:

Gigabyte GA-P45-UD3P motherboard with F7A bios
8GB of G.Skill PC-8000 BPQ memory
Core 2 Quad Q6600 @ 3.78Ghz (420 * 9X) @ 55° load
Thermalright Ultra Extreme 120 CPU cooler
Corsair HX620 Power Supply
Samsung Burner
Western Digital 640AAKS main drive, Samsung Spinpoint 1TB storage drive
Windows Vista Ultimate x64 SP1

To my surprise, San Francisco RUSH on my system runs fairly playable with some sound stutters here and there. After some tweaking with my wireless xbox 360 controller I can actually control it pretty good. It's too bad Rush the Rock gets stuck after you select your vehicle, that would be quite fun to play. I tried pressing the view buttons during the track/car selection to enable 'Solo' mode and disable 'Drones' but I guess they are correct when it says "You will not get this game working don't even try." I also messed with the service menu settings for too long which didn't help. I doubt there will be a fix anytime soon but until that day I guess I can keep on playing the 3 tracks on plane ol Rush!

What Mame version are you using to play Rush? Are you able to get the sound synced up? If you haven't already try using Mame.121 (64-bit), it's about 10% faster in Rush than other versions that I've tried. I use MameUI .121 (64-bit). Another thing is, the actual arcade had 4 channel surround sound, I wonder if their is a way to get that hooked up in Mame instead of 4 channel sound only coming through 2 speakers.

If you go to YouTube and search "Mame San Francisco Rush" you can see my Rush videos, I have tracks 1, 2 and 3 on there now.

I am using the 64-bit version of MameUI .121. Maybe that's why its so playable even though my cpu is under 4.0Ghz. The sound has never been synced up before and according to the menu in Mame, I have launched/played it 35+ times. Do you know what exactly is holding up Rush the Rock after you select your vehicle and it is flashing "Preparing Car?" I wonder how hard it would be for Aaron Giles or whoever is working on MAME to fool the game so it thinks the settings are correct or whatever so we can play it!

Bigtymer781:
I've messed with Rush the Rock too, after you select a car the race never starts because it relies on networking even in single player mode. That's kind of weird.

But, if you want the sound to sync up in normal SF Rush try this...

What you do is start the game, go into the general MAME options by hitting tab, go to dip switches and enable the "Boot Rom Test" dip switch and exit the game. Start the game again,when the Boot Rom Tests menu appears exit it, the game will restart and the menu will appear again, exit it again, when the menu appears for the third time go back into the general MAME options and disable the "Boot Rom Test" dip switch, then exit the Boot Rom Tests menu, the game will restart and now just hit abort to skip the steering wheel tests and when the game starts the sound will be synced.
