This is an awesome achievement, but I can't help but notice that Quake ran smoother on my Pentium-133 PC in the 90s than it runs on my Mac M1 Pro...

This engine is not optimised for performance. It's using CSS, after all.

Yeah this is a case of “not the right tool for the job”.

It is awesome though.

Of course, but you'd think after 30 years the compute power should be enough to overcome any lack of optimization. It's a testament to the engineering that went into the original Quake engine.

Decades of optimizing a toaster to make better toast will not make the toaster any better at making meatloaf

Is this the right analogy? The product is the same, the appliance is different.

It should be "Decades of inventions from toasters to IOT AI Smart Air Fryers will not make better toast than the original"

But I'd argue the IOT AI Smart Air Fryer should make really good toast. Which is what GP is saying.

I am on the ground. This is great.

Still, why css is as slow as it is given what tech like imgui can do is a little wild.

CSS is a general rendering solution, not something built for rendering 3D games.

And no one has spent any time optimizing 3D transforms to make a game workable because no one would be able to justify the use of their time like that. It wouldn’t even give you brownie points ‘cause most people would just ask “why?”

Id assume "a fun challenge" could be enough of a reason

For what it's worth it works like smooth butter under Chrome on an M2, on Safari it's clunky and seems to clip alot

Either you had a Voodoo on your P133 or whatever the M1 is doing is having a bad time...

On my 7945HX this is plenty fast.

Wait, did Quack run on Pentium-133? I had a Pentium MMX 233mhz and I always assumed it didn't ran well so I never bother to get it.

If you had a 3dfx card it would run silky smooth on a Pentium-120 (what I had at the time)! Quake 2 ran pretty well too if I recall.

Bare minimum for it being playable was a 486DX4 100MHz or similar, but with the floating point Quake really wanted a Pentium

I played it on a Pentium with 60mhz - it was allright

Ran fine on my Pentium 90 with 16MB RAM

It must have, because that's what I had in 1996 and I played it.

Quake ran on a P75 with 8MB RAM in DOS mode. Not the best but it worked at 320x200.

Quake ran well on my 100Mhz Pentium.

I think you’re missing the point
