Well, Sam and Max Seasons 1 and 2 ran just fine on my machine, so I was a little disheartened to find that Episode 1 of Season 3 barely runs at all. The animation and sound lags horribly, and the mouse barely moves at all on the menu screen.
I checked the game's system requirements, and none of my system's specs looked out of date except for my memory -- the required amount of RAM is 1 GB and I just have 0.99 GB, but that hardly seems like a deficiency that would impact this game's performance that much.
I've tried updating DirectX and my Nvidia video card's driver, but it turns out they were already up to date, so that didn't help. I noticed a few other threads here reporting similar problems with replies asking the original posters to post info obtained from the DirectX Diagnostic Tool. I might as well do that now to save myself the trouble of doing it later.
Any additional help would be greatly appreciated.
EDIT: Sorry for not mentioning this before, but I'm running Windows XP SP3 on a Pentium 4, 3.06 GHz, 0.99 GB RAM.
