OK, I've played quite a bit of it now. Seems to run fine on my P4 3.2 OC'd to 3.5 w/1 Gig. RAM, Asus P4C800E Deluxe Motherboard and BFG GeForce 7800 GS OC 256mb 8X AGP. Automatic game settings are all on HIGH including 4X antialaising at 1024x768 resolution. Every now and then when I enter a new area with lots of lighting it might hesitate for 1/100th of a second, but mostly it's smooth as silk. Turning off the antialaising would probably get rid of that hesitation, but its not bad enough to worry about.

The program did tell me I don't have the latest video driver installed but I haven't updated it yet. (If it works, don't fix it!) At times I've found that an older driver (but not too old) works better on a particular system for some things.

Haven't had any sound issues either. I'm running a Sound Blaster Audigy2 ZS Gamer sound card in 5.1 Surround.

HL2 is very demanding on your system as are most newer games ( ). All I could suggest without knowing more about your system is to lower the video settings. Turn off AA, HDR, lower Anistropic filtering and try playing on 800x600 or 640x480 resolution. You might try setting the sound quality to low also. It could be that some of the sound issues you're having are due to the graphics problems.

Give us some info on you system... it might help diagnose you probs
