0.148 multi-threading enabled by default

i notice in the list of mame 0.148 changes that multi-threading is now enabled by default in windows
i thought multi-threading was experimental and sometimes cause issues, or is that in the past now
ps. anyone know if later gen pentium 4 hyper threading cpu's see much advantage with mame multi-threading enabled or 'not really' (i will do some tests myself in a couple of days but interested to hear any thoughts on this)

I've had it turned on for ages, and I've never seen any problems. I'm running an older dual core AMD, I actually need it to get some things running at full speed. As I recall, Donkey Kong has issues for me with multithreading off. If it's on by default, the devs must be pretty confident of it as well.

It's worth trying, but I wouldn't expect too much. HT is somewhat useful for reclaiming cycles from apps that leave the CPU idle a lot, but for code that is fairly tightly written, it doesn't do very much. I suspect MAME keeps the CPU busy enough that you won't see much improvement.

I leave it off. This motherboard doesn't have hyper-thread option.

I always assumed multi-threading took advantage of multiple physical cores as well as virtual ones.
With a Q6600 wouldn't you want MT enabled?

Never work right with the other stuff enabled in the mame.ini. MAME works just fine without it. I haven't got around with the 0.148 yet to see the problem is gone.

I have to leave multi-threading off as it causes really bad lag with usb trackballs when used with v-sync.
