AGA Games, Sound brakes up on ASUS Eee-PC

[Vars191]

Hi All
I have tried winuae on ASUS Eee-PC 900 to 1000 models and all have the same problem, when you try to play AGA games like Aladdin or Fire and Ice the sound brakes up, tried making sound buffer bigger, slight improvement
also tried mono and different bit rats and different combos
any ideas?

Did you try less accurate sound emulation.

[Vars191]

Tried that also, no joy

What resolution are you running? Have you changed windowed/fullscreen and was the result the same? More info please

800X600 window tried full screen no difference, only when I strip windows XP to bear bones it sorter works

So just performance issue right? Would have guessed it. You could go for 640x480 or 720x576 in windowed mode. Also you could try 320x240 in fullscreen (disable double line mode). Not sure if this will display nicely, but it could improve the performance

Just tried it, fail

AGA emulation requires much more CPU power than A500. Try enabling JIT but most games aren't very JIT compatible..

also have in mind that the Atom 1.6hgz cpu performs similar to a 800-900mhz celeron cpu...

That sounds like the problem, not enough horse power for AGA emulation

Overclock it?

and a useful eee utility for OC

http://www.cpp.in/dev/eeectl/

The eee-PC 900 is only 630MHz celeron from factory. It is possible with this utility or a BIOS update to run it at 900MHz

It is the Atom CPU not the Celeron version.

OK... I believe this utility allows for overclocking on the Atom as well...

The eee 900 is Celeron, the eee 1000 is Atom AFAIK.

But the Celeron used is a 900Mhz underclocked to 630Mhz. Isn't the Atom designed to run at 1.6Ghz and is clocked to that? Any extra may cause extra heat that can't be dealt with by the cooling of the EeePC?

[NewDeli]

May be someone could lend an eeePC to Tony (or to one of the beta-testers), so he could examine more precisely how WinUAE react to the low-power Atom CPU oddities.

Tis true, however the utility also allows for manual fan control. Most laptops are designed to survive a little extra heat anyway - look what happens when the heatsink on them gets a little fluffy! As long as you keep it on a good surface (ie a table, not a carpet or bed) and keep it nice n clean you should be OK.

I would only increase speeds by a small amount - at least you might get better performance from it then...

Nice! I did overclock my Eee 701 to 900 in Windows but i wouldn't be as keen with the Atom. I personally would knock down the screen res and sound quality output to get better performance. But it isn't my Eee!

I assume its still under warranty? If you are overclocking in Windows and you fry it - just claim on the warranty... how can they tell?

[Toni Wilen]

Atom seems to have small cache which probably explains slowdowns (emulators really want lots of cache and fast memory)

I still haven't seen any numbers. "sound brakes" isn't something i'd call useful information...

Does JIT help? (try some game that does not hate JIT too much)
What does SND% and CPU% show? (windowed mode) CPU%>100 = not enough CPU power to emulate current configuration.
Try enabling lores and non-doubled mode + use filter to double the size. (may use less CPU)

NOTE: In 99.9% cases the problem isn't sound. Bad sound is (too) easy to notice. Not enough CPU power = not enough sound data available = previous buffer repeats.

Overclocking is not covered under any warranty. If the technician finds the computer as fried because of overclocking (and they can rest assured), you stay with a nice brick on your hands.
