So this is a pet subject of mine, I posted about it a few years ago but was content I had solved the problem [ie. found a kind-of solution and moved on].

Warcraft 1 plays on my Athlon/Voodoo5 box ok. Except that I get little flashes appearing on certain graphics, and building outlines flash too fast. The latter is due to computer speed it seems [though the game itself does not play too fast] as can be proved by playing it on a slower box.

But the little flashes of white look crappy, I want to get rid of them. I tried these cards:

Voodoo 5
Voodoo 3500
G200

all show this symptom. This is running under DOS or Windows. Today I tried on my 486, arghh! I notice them on an S3 Trio and an S3 Virge, though not as bad as the Voodoos.

So I try them on a Wildcat VP760 card - this is an old workstation openGL agp card [dx8.1 compatible too, but try playing Diablo in 800x600, runs at like half speed], which has excellent quality for some things. Wow, warcraft 1 is glitch-free, none of those damn flickerings.

I don't get it, what can be going on here? They are all using the same monitor and kvm cables . The fact the wildcat works shows its not the kvm or monitor[or any interference with the cabling - I did find that my Phenom box caused interference in nearby computer graphics once upon a time, but it was off during this testing], nor the athlon box itself as thats what I tried the Wildcat in. Is there some signal strength issue, some tolerance somewhere that consumer-level cards are a bit looser with?

Makes a difference to me because I rank visuals greater than crappy music [and I think warcraft 1 music is pretty naff whatever I play it through - gus, roland, yamaha, whatever]. So the 486's days could be numbered here, as I am starting to value space over recalcitrant equipment 🤣.

Dosbox incidentally is glitch-free [even on the voodoo 5 on the athlon] but the slight input lags make me want to also be able to play the game natively.

So far I haven't seen this effect with anything else but this is the only game I play that's from the pre-486 era as far as I know.

Update: I muffed up my graphics card swaps and ended up leaving the Virge in my 486. Now I get these same glitches in Heretic, all over the place. Haven't seen that elsewhere, Heretic is usually fine.

Ok, I've tried that now, thanks. I tried both the athlon and the 486 with 2 different cables direct into the monitor, same symptoms. One of these cables was a new one not previously used with the KVM.

I also moved the 486 to a different room and plugged it [directly] into an LCD monitor, using the cable that was in there. Same symptoms.

That seems to rule out the monitor or cables as the problem, though I did find one of the KVM junctions was falling apart 🤣 but that clearly wasn't the problem. It also rules out interference from other equipment near my main computer area.

I'll put the S3 Trio back into the 486 and see if that gets rid of the problem with Heretic.

With warcraft 1 it seems to get really bad when you select a building for the peon to build - the town hall gets interference on it, maybe this is related to the fast flashing of the building outline. Some component producing interference inside the PC itself?

RG100 looks up the word recalcitrant in a dictionary. Personally speaking, that wins the "awesome word of the day" award. 😀

🤣

Anyway, I put the Trio back in the 486 and that gets rid of the glitches in Heretic. Guess the virge might be faulty. Doesn't solve the interference in warcraft 1.
