Re: Maybe create a set of recommended system profiles?

That's........already what it does. A lot of this is frankly overkill for dragging the video card from CGA and sound card from none in their combo boxes.


The only preset profile I can realistically see is one for an Xi8088 PC for downstream convenience/compliance of a basic open XT clone.

Re: Newer X-Wing Games and PCem

I don't have those later X-Wing games, but have you tried slightly earlier Voodoo2 drivers pre-DirectX7? I.e. V3.03.00 The DirectX 7 beta (V3.03.00b) and latest V2 driver (V3.02.02) makes some Direct3D HAL regressions with a few late Direct3D games like AvP which came around the time of Alliance, fo...

Re: CD Image Format - Blindwrite

I don't think supporting many specific proprietary formats are the way to go though.

Re: Serious performance issues

You might also want to look into trying the ATI Mach64 as well, which emulates faster for me but i'm not a fan of its textmode fonts.


IIRC Win95 doesn't ship with a TGUI9440 driver, though DirectX 3 should have one.

Re: Some Lag On Some 2D Graphics

The software rasterizer in Microsoft's OpenGL32.dll was always slow though. it's kind of a miracle they squeezed that performance - while being perspective correct - out of 3d maze on a Pentium at all! The video backend you choose shouldn't matter for the screensaver as it's going to through to GDI ...

There's also the particular textures you have picked. The color cycled ones likely involves a per-frame texture process + upload.

Re: Some Lag On Some 2D Graphics

3D Maze is performing as intended. Note that all of the Windows 95B+ OpenGL screensavers are ALL software rasterized and render in true color. You cannot accelerate them. If you recall it being faster on a computer of that spec, it's likely the low-res mode. (later down the line, XP did accelerate t...

Re: PCem is still open (background process)

The only incidents i've seen it 'stay open' is when closing off a 256mb machine and quitting really fast probably during dump. This has bit me a couple times between rapid compile+test+change+compile cycles during development.

It's possible - if you're willing to write code and program the chipsets they expect. You can't simply just drop any rom in and expect it to function.
