Ok, so I’ve been converting the Quake III Arena installs on all my machines from id Tech 3 to ioquake3, but on one of my machines, my only Windows XP one, the game runs **everything** at less than 1 frame per second.

I’m not talking about just in game, either! The logo animation runs slow, the movies run slow, and I can’t even type things into the console at a reasonable framerate. I don’t know what’s going on, if there might be a bugfix for this that I havn’t heard about, but I’d really like to know what’s going on.

My other two machines run Windows 7, and ioquake3 gave them a 5-10 FPS boost, but the engine is really dying on XP. The task manager says that it’s using less that 5% of my cpu power when idling, so maybe my GPU is too old. My computer is an HP Compaq 6510b, my CPU is an Intel Core 2 Duo T7100 @ 1.8GHz, my GPU is an Intel GMA X3100 atop the Intel 965 Chipset Family.

Thanks in advance for any help I get about this

Sorry for the late reply.

Do other 3D accelerated games run?

What version are you using?  
Please make sure to use a test build:

> **[Test Builds](https://ioquake3.org/get-it/test-builds/)**

> Please see this notice for information on why the test build are missing and when they will return.

It sounds like your video chip on that machine doesn’t provide hardware rendering and you’re getting software rendering instead. You might want to check with the HP/Compaq megalith and find out if they have an updated video card driver.

I can run Quake III Arena with the standard engine, it’s ioquake3 that’s running slow. It’s utilizing less than 5% of my cpu, too. I also have the latest drivers; I did a system wide megaupdate 3 weeks ago.

I’ll try the test build though, thanks.
