FS-UAE with A1200 emulation on netbook

I thought i'd try this on my friends netbook! It seems to work great on A500 stuff but when we tried some A1200 AGA games some played slightly slower (probably due to his 1.6gig processor but it is Dual Core). We also tried WinUAE but it made the sound horrible. Is auto frameskip a possibility ?

A1200 requires significantly more CPU to emulate then A500, so yes, the problem is most likely a too slow CPU. Is is reasonable to assume that the sound problems in WinUAE is caused by the same problem (audio not being output fast enough).

I have not really considered auto frameskip (or frameskip at all). Sure, there will be some resources spared by not having to render a frame, but the frame has to be *emulated*, and emulating the 14Mhz CPU in the Amiga 1200 is what's causing most of the trouble here.. (so frameskip might not help that much?).

I don't know if you have already tried it, but you should first try to get FS-UAE to use a little resources as possible, for example:
Code:
accuracy = 0   (or -1)
video_sync = off
video_format = rgb565
Reducing accuracy will have most effect. video_sync will make the rendering process a bit easier for the system, and video_format = rgb565 should speed up rendering / texture transfer.
