Is the speed problem better in earlier builds? If so, can you tell me which build introduced it? Guess I'll have to get inside and see what opengl calls can be moved to the init section. Unfortunately, OpenGL-HQ needs more initialization calls, but that shouldn't affect opengl/openglnb. And yes, I …

How did you run the game? I.e.: What did you click, what did you type, everything you did. What other games did you try? What version of dosbox are you using?

Hmm... I may be wrong, but OS/2 might have an int13 disk driver, even though it has no DOS underneath. I vaguely recall that from the days I used it. Will try it one day 😉

The best indicator is "sound continuity". Play something with sound and check that sound is playing fine. If you experience dropouts/stuttering, your cycles are too high.

ARM, not PPC, and "not at all yet" - I usually pick these things up as I go. I didn't know anything about OpenGL either, when I started the hq scaler 😀

It should be. Since I now own an iPAQ, that's something that fascinates me too, but it's not easy at all. I have no idea how long such a task could take, I expect many weeks of coding and testing.

Indeed, not terribly useful but still nice to hear it works 😉 The refresh delay seems to be an ATI peculiarity, I see it too. There's a lot of memory freed and reallocated on a resolution/fullscreen change. I guess that takes some time when the GPU is involved.

Typical PDAs run an ARM CPU at around 400MHz. If it had an x86 CPU (it doesn't), that would be enough to play most non-actionshooter games using dynamic core. Since dynamic core is not available for ARM CPUs, the observed 3000 cycles in normal (simple should indeed be a little bit faster) are to be …

You know, seeing things like humans do is an astonishing difficult task. For any given 2d picture of a 3d object, there can be multiple 3d representations. Humans usually choose the right one (not always: check out my favourite artist Escher), but computers can't - they lack real life experience. On …

You'd also need some SDL output method that works for you. Try "export SDL_VIDEODRIVER=dummy", it seems to route all output to nirvana.

You mean by using fullfixed=true and fullresolution=320x200? Don't do that... it's quite hard to squeeze 640x400 pixels (like the DOS prompt uses) into 320x200 pixels 😀 Why define fullfixed at all? Setting it to 320x200 is as useful as not using it.

Sorry, there's no way to do that. DOS games are not 3D. Never ever. They render to a 2D screen. Some have internal 3D calculations (surprisingly, DOOM does _not_ do that), but that's something that is part of the game being run. DosBox only sees 320x200 pixels. You're right, if it's flat shading, we …

Strange, I just disabled the problematic NV extension. Do you have a screenshot? Probably just a bad build, though. Sometimes the tables are not generated correctly while cross-compiling.

You could at least try frameskip 1 in order to compare software scaling to openglhq. That would show if it's something specific to your machine or if it's the same behaviour I see here. Also, do you have some other CPU-heavy game? I don't have any game of the TES series, so I can't compare/test …

Openglhq is slower that plain opengl, even though most of the work is done in hardware. I found it to be comparable to software-hq2x, but with arbitrary scaling factors. x4 scaling (4 times as much pixels as x2) at the cost of x2. Another reason could be that on windows, ATI gives me 16-bit-per- …

HunterZ, it was common in Win 3.0/3.1 days. Programs that needed windows would simply start it by calling "win " (from the MZ stub executable, just like win9x programs print some kind of "you need windows" message). And that actually worked. Win 3.0/3.1 could run a single executable directly that …
