Still need to bench it properly but so far switching to the 5428 instantly doubled my frame rates in Doom compared to the old card 😳 so that’s quite the result there.

I did have a bit of a panic when it displayed garbled colours on booting into Windows until I ran Setup and figured out I’d forgotten to switch from the old Trident drivers…. 😂

Nice!

I guess I stumbled on the Phils CL vid yesterday that has a lot of ppl saying they're "No" faster, when he did a test with a DX33, which showed them faster but not by a lot. But then in another vid he did them with a DX2-66 which spread them out more. Though strangely first vid is labelled with DX2 33 in the title. Basically discovered that slower CPUs are the bottleneck in more demanding games (Whodathunkit?)

It's quite hard to imagine isn't it?

And for the record Dos/Win3.x were faster on my Pentium 133 than what they were on my 286/16. Really a magical phenomenon....Can't explain it at all at all.

While reading through this thread a bit I was wondering, would it be possible for a VLB video card to operate in a 16 bit ISA slot? I have ATI Wonder 16 VGA card that works in either an 8 or 16 bit slot, so maybe the same applies to VLB video cards? Just wondering, maybe it depends on the card, dunno. I guess it could be interesting in terms of bench marking a motherboard, vga/chipset and cpu combo, testing on the same hardware. I see a lot of benchmarks are testing against with different graphics adapters and even though we already now that ISA is a bottleneck and slower than VLB, doing that test with the exact same card in VLB vs ISA would probably make more sense? I dunno, just thinking out loud...

Generally no. The extension part on the VL slot with the higher contact density is a completely separate bus from the ISA bus. On (nearly) all VL graphics card, the graphics chip is connected to the VL bus only, and is not accessible through the ISA bus. Often, the video BIOS resides on the ISA bus (it's usually 8-bit only anyway and so slow that ISA doesn't hurt), but that's usually the only stuff on the ISA bus.

Yeah it’s a pretty conclusive result I would say, it’s actually just over double the FPS. Wonder if it’d be even more of a drastic difference with something like a 5x86 in there. It does turn out the CPU can be a bottleneck after all 🤷🏻‍♂️

I saw a bench somewhere between the exact same chip in both VLB and ISA form and it was pretty decisive but never a VLB card in an ISA slot. As per the above post I wouldn’t expect it to work. Maybe I’ll see what if anything happens tomorrow.
