Hi guys
permit me in lieu of my more commonplace sobriquet, to post a puzzle.
Scouring these very threads for info, I have come across a function in MAME that allows a quite glorious imitation of the aged CRT monitors.
I am of course, referring to the HLSL functions and presets you can enable in the mame.ini file.
The puzzling part is, when I enable these functions, the system slows down to 60% of normal speed. I initially thought the system was too slow to run these new nostalgic graphical inclusions, but when I disable the throttle (F10) the system speeds up far beyond normal speed (100%).
So, either the system is too slow or too fast with these scan lines enabled.
I have no such problems when not using the HLSL functions.
Has anyone come across a similar problem? I trust that you will not be disinclined to acquiesce to my humble educational requests.

CPU is Intel E3300. (basically, core 2 duo @ 2.5 ghz)
Video Card is an old Geforce 6600.

The 6600 is the problem here as it lacks the horsepower that HLSL needs and requires.
If I remember correctly you need a 9XXX or better.

Thanks for the update B2K.
I will upgrade the graphics card to something a bit more worthy lol

Would a geforce 210 be sufficient to run hlsl preset 1 without any issues?

I'm not sure on that. I recently upgraded my GTX 480 to a GTX 760 and both runs whatever I throw at them.

What is the explanation of that behaviour? If the video card doesn't have enough horsepower to do the regularly-emualted rendering I'd expect the disabling throttle will not help much... Any clue ?
