Not useless, but games made to use the CPU mostly are what this laptop is best at.
It might run TF2 if there was enough RAM to allocate. on 32-bit you can only use 3GB.
You'd be better off running the graphics with the CPU maybe, if it still much more performant
But yeah i'm genuinely surprised my oldest laptop isn't far behind my beast desktop when it comes to running Half Life 1 on CPU mode
I guess you can offload a bunch of stuff to it so not completely useless
Then I figured, it must be because HL1 must be putting all its load into a single core
Genuinely I'd be willing to see how the gamers in 2003 played the game lol
The Intel Celeron was just a Dual core, so half of it is a lot. my current Ryzen 5 5600 must have plenty more cores and therefore an individual core isn't that much better on its own.
Well, hopefully 2003 gamers weren't using a CRT TV on Scart like me, but a CRT Monitor with VGA.
I've yet to find one of those wonderful screens.
And also remember, i can't always control if a game uses the CPU or GPU on my old laptop.
It's not like modern laptops having 2 GPUs and can switch them around at ease.
XXL1 is definately a GPU accelerated game, but thankfully it has been coded so well that the requirements to run it are tiny.
Half-Life can be controlled by choosing between Software or OpenGL/Direct3D mode.
You could potentially with a little fiddling, but it is not simple
They made a whole engine for it and for the subsequent games
KAL engine is probably one of the best engines made from France ever.
