WinUAE Documentation



On a sufficiently powerful PC, UAE will give you quite an authentic flashback into the past. Thanks to DirectX, the raw drawing throughput of this version will be among the highest of all Intel ports.

Use the tips below to maximize the performance of your emulated Amiga.



As a rule of thumb, WinUAE needs 60+Z3+Chip+Fast+Picasso96 MB of system memory.
Since WinUAE 0.8.17r1, memory is allocated dynamically. This means you can select 512MB Z3 Mem and find no difference in boot time, but if you work with UAE for a longer time, it may get very slow. So it is better that you calculate your RAM needs with the above formula and make sure that it is lower than the pysical limit. Windows has to store the data on the harddisk if it runs out of RAM, which is a gigantic performance hit.
Also try to activate "Suspend to Disk" mode. UAE and Windows will be ready to use within 30 seconds. Do not forget to use the timehack to set the amigaclock to a correct value.



When using Workbench, it is strongly recommended to make use of WinUAE's Picasso96 support. Using this, you can utilize the power of your PC graphics card to display higher resolutions, more colors, and give all graphics output a significant speedup.

Read more details about the correct usage on the Picasso96 page.



Sound is a luxury in emulation. Because sound output is synchronized with video DMA, you won't get clean sound unless your machine is capable of running at 50 fps at least internally. Again, if you are using the Workbench, it is recommended to use AHI as your preferred sound interface.

If you use programs that need no Paula, set sound output to "Disabled, but emulated". To hear system sounds you can use ahisyssound found in Aminet.

For a further speedup, use ahitweak. Increase the poll rate (the rate WinUAE checks for soundbuffers). Default is 40, but in most cases can be set to 60. Set the sound buffer 4 or 5 in the Sound tab.



Use hardfiles as your main drive to avoid trouble and better speed during disk operations, for numerous reasons:

It is recommended to install the AmigaOS and programs on a hardfile, so the access and backup can be done quickly. To store pictures and other data, you may use a Windows directory for easier data exchange with the PC.
Transferring data from/to a hardfile can done by simply copying it, so you don't have to install all your Amiga stuff again.
