After testing my 486sx/16 with a GD5422, I found it to be particularly slow.
Do you think that an accelerated cirrus chip like the GD5434 would be a better choice for such a machine?
Possibly but thats a slow CPU
For what its worth in my testing their is no performance disadvantage in any situation vs the renowned ET4000 but hardly any of those were 2D accelerated, as you can see in my youtube video its not a stuttery mess in windows like an unaccelerated card so it has all of the benefits of the ET4000 but the advantage of 2D acceleration, can't fault it as an ISA card and theirs not many options, you have to get lucky to buy a good ISA accelerator card for a fair price these days.
I think occasionally you'll see a Cirrus Logic 5428/29/30 pop up and these are still a good option, otherwise very rarely a ET4000 W32/i/p or the ATI mach 32/64s equally as good(I think).
The other issue if like me you want a 2meg card not always possible.
I tried an earlier S3 924 its performance is crap in dos unfortunately but does accelerate 2D, 928 might be an improvement not sure.
I would say the WDC chip cards would be okay but may not find 2meg.
And matrox pretty rare and expensive I've got no experience with those ones.
