Does disabling ACPI could improves video/graphic performance? and what is the down side of disabling it? can explain it to me...

Thanks...

From everything that I have read, it's not worth it. Typical gains in 3dmarks are in the 100-300 range and then you have to manage your own IRQ's. I'll take the convenience of ACPI over a couple hundred 3dmarks any day.

So it does improve performance? coz right now I'm running with ACPI disabled, and If I re-enable it through BIOS, I have to re-install windows... that sucks...

I'm glad I don't have to assigned the IRQ manually by disabling ACPI, but my system cannot goes standby because of it...

Any other experience guys by disabling it?

Some games like disabling of it, some don't...basically it's a crap shoot, and basically it was over-hyped...put ACPI back on...

I've just run a quick test, I've just re-install windows twice with ACPI enabled and disabled...

And I've decided to turn the ACPI off because from that quick test I've already encountered 2 things...

1. If I enable ACPI and playing mp3 with my winamp, sometimes it skips or pause when I'm doing something else, ex. browsing the net or my folders... while when I disable ACPI I've never encountered those kind of problem...

2. When ACPI enabled, I've experienced a bit jerkiness when playing MOH:AA and GTA3, while with ACPI disabled I didn't experienced such jerkiness... I didn't test it with other games, coz that 2 games is the only game that I've played often...

I've installed the latest drivers except for VIA 4in1, I never trust it, VIA driver which comes from XP is a lot better in my experience...

Well, that's my experience, and disabling ACPI doesn't seem to hurt my com, the only problem is my system cannot goes Standby, but I never use it anyway...

Cheers...

I hace ACPI on with ESCD on manual...which means, as far as I can tell, the IRQ goes normally instead of all in one.
Which (assumedly) means I get the benefits of it off with the benefits of it on. Heh heh.
I also have APIC 1.4 on, but anyway
