I have a Pentium MMX 166 with an S3 Trio64V+ 2MB and Win95 OSR 2.1 runs smooth as silk.

You might have a driver issue, or maybe some hardware setting needs to be changed. Is an IRQ assigned to the graphics card in the BIOS?

Windows and HWInfo show IRQ 14 is routed to it, no conflicts anywhere on any devices.

This machine used to have an ATI card in there, so maybe it could be a driver thing?

Just to clarify, it's perfectly usable and games like Dungeon Keeper seem to run just fine.

When I'm finished with day job work, I'll reboot to Windows and capture a video of what I mean, maybe I'm just not explaining it right or I'm expecting too much 😁

Was Windows 95 always like this?
When I was a teen using this exact machine, I remember exiting games and watching Windows re-draw the desktop line by line because back then it only had 8MB RAM, the on-board 1MB SIS 6205 VGA and a slow IDE disk, but I don't seem to recall having these kind of issues.

I don't know, I have no real comparison since I "grew up" with Windows 95 RTM on a 386DX40 PC.

I believe I haven't really seen a Pentium until the Windows 98 days.

(I mean, sure, I have seen them running DOS before, of course. Pentium 60 or 75s etc.
But these were power user systems.

The PC shops in my city had them on sale, too, running some demo applications..

It wasn't until Windows 98 that the average home user in my neighborhood had a need for a Pentium so desperately.
I've seen Windows 98 crawl on 486DX2-66 PCs.)

To me, Windows 3.1/95 always had been 386/486 territory, with ISA or VLB graphics cards.

From what I've read, I thought the ViRGE series (incl/GX) was king of Windows GDI acceleration?

Not sure. I would have thought that S3 cards are generally speedy.
Since the S3 Vision, at least, which was the predecessor to the popular Trio series .

I merely collect S3 ViRGE 325 cards because of S3D support on DOS..

So I guess it comes down to a number of things:
Is the CPU too slow for good 9x speed?
too much RAM? Since I have no COAST module.
Is there a better Direct X 5 PCI card? Maybe 4MB Rage II+DVD? (I have separate machine for DOS).
I only have the one slot so a Voodoo is not possible and the Rush is very expensive 🙁

Hi, I don't know. You could try to replicate the setup in PCem/86Box and see how it goes. 🤷‍♂️

Is the IE 4 Active Desktop update installed? It makes the desktop redraw at a fairly slow pace.

@GemCookie, It doesn't appear to be, I can't enable it from the Desktop and I don't see it in the Windows Components or IE Setup.

DirectX 8 4.08.00.0400

Maybe it's related to DirectX8 somehow?
I know that Windows 9x uses plain GDI, but still..

Back then when Windows 95 was new, there was DirectX 2 or 3, which had shipped with DirectX-enabled graphics drivers for S3 and other VGA chipsets.

And in the Windows 98 days, DirectX 5 or 6.1 was new.
Windows Me had DirectX 7.1.

DirectX 8 seems waaay to new for Windows 95.
It remember it from when Windows XP SP1 was new.
