Half Life 2 not running as well as it should?

[Gimpymoo]

I seem to be getting stuttery gameplay at any resolution, it just does not look smooth.

Specs:

AMD A64 3000+
2GB RAM
ATI x1950 PRO 512MB

Happens at all resolutions.

Am using latest video, audio and chipset drivers.

Any ideas?

Installed via steam (Clean install) so should be most upto date?

Thanks all.

The -heapsize switch on launch appears to have helped.

Set to -heapsize 10240000 has have 2GB Ram.

Will keep updated.
