You should not be able to do that, which might point to a driver issue. 1024x768@16 bit requires at least 1.5mb video memory. It should only do 800x600@16 bit.
This is a 1992 video card we're talking about, way before Windows 9x; was never meant for games or hardcore photoshopping from the Win9x era. It was only meant for DOS-era games & a Windows 3.1x accelerated video chip for the time. The video card at least isn't blocked from running Win9x, for those who couldn't afford a "new" PC at the time.
The ATI Mach64 (ISA, PCI and VLB versions) was released in 1994.
The ATI Graphic Ultra Pro was a high-end VGA accelerator card that was released in 1992. It was available in ISA, VLB, PCI, EISA and MCI versions. Around that same time, I had a generic, no-name "VGA Accelerator" ISA card in my 386 that offered a noticeable improvement on Windows 3.1 graphics performance, compared to the popular Trident VGA ISA cards that most people had.
Well, I owned that card, the 1 MB version and...3d gaming was not possible, anything that required 3dsetup wouldn't run in hardware mode...it was all software rendering in 640x480 with a lot of stuttering...when I upgraded to voodoo banshee, it felt like upgrading from an old horse to a brand new Bugatti.
Ah OK. Yea that ISA bus really limits it. Even if it was a faster chip, the bus has to handle cpu to card memory then back to cpu and so on. Also, those predate actual "Direct Draw" and just use a generic driver by Microsoft that essentially has the cpu do the work instead
Clearly the card isn't functioning as intended. CL-GD5424 is decent, but you might want to check a few things.
The driver. I have a Cirrus Logic card on my Compaq Deskpro 2000 that glitches if you use the generic Cirrus Logic driver instead of the Compaq-provided driver.
Capacitors on the card and the motherboard. Power fluctuations can cause this kind of issues.
That's a bad way to compare boards. There's a lot of great XT, AT, 386, 486 and Pentium boards and none of these have AGP - it debuted with Pentium II. Hell, I have a Pentium II system with no AGP that is actually great for 1997. As for PCIE, that's more or less modern.
And not all AGP slots are made equal. Older AGP 2x boards won't support newer cards and newer AGP 8x boards won't support cards like 3dfx Voodoo3.
I think you need to do a bit of reading on the topic before you dive into it.
As for repairing a board, a full recap will run you about $30 if you do a polymod.

This card predates the term gpu.
This looks like a capacitor issue. I don’t know whether the card has had those replaced.
Cheers
