By "moving around" I mean if the view is changed. (like turning 180° around)

BTW here is the text of the "section" below the "Start game" button in the glidos main window. Shouldn't be that different compared to the configurations of other users:

Oh well done ATI! Yes I see exactly the same on my X800XT. I might try one version back on the drivers.

Strange one this. I've disabled the calls that make the DOS window disappear and make the Glidos Window the foreground one. That way I can run with keyboard input going straight to the DOS game, rather than having Glidos route key presses from the Glidos window to the DOS window. Running like that there are no momentary freezes.

Hmmm, and in normal mode, every stutter is accompanied by the game reporting "limited 5".

Think I might be on the way to fixing this. I've created a version here with all the mouse handling turned off, and with the key presses excepted directly into the DOS games window. That works with no stutterin, provided you don;t move the mouse over Glidos's window. But move the mouse and, although Glidos isn't picking up the mouse mesages, it stutters away.

I think its because Glidos does all its OpenGL rendering in a separate thread. That thread plus the game itself completely max out the machine, leaving little left for processing the message loop in the main window. I think I need to get the whole thing running in a single thread. Its a guess but I think it may work.

It works. Can play D2 on my x800xt at last. It'll take a little time to tidy stuff up, but its more or less there.

Now fixed in v1.30, just released.
