Cannot display 16/32-bit mode at 1680x1050

chocolate_boy · 13 June 2010, 17:42

For some reason I cannot display any higher than 8-bit at this resolution which looks pretty poor.

Oddly if I launch WINUAE from my Amiga forever disk, select their default it works fine at 16 bit, but when when I load my config it's only 8-bit.

To make matters more confusing, if I load the Amiga forever WINUAE expanded config, then replace the hard disk with my file, it's there as well.

How do I enable these modes for my config?

Most probably you are assigning too little RTG memory the higher the resolution and the collors the more ram the graphics card is going to need.

Hmmn when I increase the RTG ram above 4 megs it seems to stop recognising it's there totally. Any ideas?

Ah sorted it, restarted WinUAE then tried. Thanks TheELF the modes are there now

Minimum RTG RAM required = width * height * bytes per pixel, where bytes per pixel: 8-bit = 1, 16-bit = 2, 24-bit = 3, 32-bit = 4.

There still seems to be some kind of memory leak in WinUAE. I've often seen it that if I increase one sort of RAM on the fly that WinUAE automatically reduces this sort of RAM to 0M (usually Z3 RAM). If I then quit WinUAE and run it again, it lets me increase the RAM without problems. The problem only happens if I change the amount of RAM several times or if I load a different config several times without quitting WinUAE.

I've noticed that also with RTG memory on rare occasions. When it happens, I set the value (32MB) by hand in the config file.

This should be fixed in next version (No idea when and what)
