I remember this running well on a low end macbook pro back then.

Here I am running just fine on a 3 year old phone

Everyone forgets what machines are capable of if you actually optimize. This game did everything shown here in real time on phones 14 years ago https://youtu.be/JDvPIhCd8N4

Have you heard of KKrieger? So yeah, if you optimize enough, machines can do quite cool stuff!

I think KKrieger required pretty beefy specs for the time. It's a different kind of optimization they were aiming for (code size Vs execution speed)

Although a friend of mine ran it on an integrated intel GPU recently and it performed great.

It's running fine (not too smoothly but ok) on my 8 years old Xiaomi MI6.

My old phone is running it at exactly Uncaught Error: This demo requires the OES_texture_float extension fps

Same on a not-old Pixel 8

Works well for me even on a 50€ (fifty euro!) chinese tablet I bought a few weeks ago.

The in suit battery driven hamdwarmer he invented it!
