179.84% at 4.5ghz ??? Wow, It's incredible !!

With my 4790k O.C.'d to 4.8ghz I get roughly 145% 😮

That's because you're on a 4970K and he's on a 6700K.

I know, but according to some benchmarks, the 4790k should get equal or even slightly better single core performance (multicore is another story) than the 6700k using the same clock rate (mine is 4.8ghz)?

If you are curious about some more comparisons see my bench page at http://www.mameui.info/Bench.htm

My nightly builds tend to be a little faster than the official builds for whatever reason.

Hi John,

sure, I'll take a look at your page. Thanks 👍

Couriersud just checked in some changes that roughly triple the performance of this driver without hurting correctness, so the next release should be better for you.

Wow! Great news! Thanks R.Belmont.
Btw. The amount of changes and advances in the last versions of Mame is just incredible.
Many thanks to all devs and congrats. 👍
