I'm having a strange problem with the game - even at 800x600, when I move my mouse (logi MX500, MW9.76) quickly in a circle, the room spins smoothly around Sam for about one rotation, then the scene skips and seems to reset itself. Is this part of the program - i.e. the camera resets after returning to a certain position, or am I having some real lag here? I'm thinking it's lag because I also have the problem on the menu screens. If I quickly move the mouse on the menus, the pointer tracks for awhile and then freezes - and then jumps to the new position after 1/2 second or so (along with a slight pop in the audio). This only happens in SC - not in any other application or game. Am I missing something or do I just lack the juice to get full-time smoothness out of this resource-intensive game?
My machine is:
Epox 8K5A3+ Mobo
2200+ Athelon XP
512 MB Samsung PC2700
MSI GeForce 3 Ti 200 VIVO
Pinnacle DV200 Firewire card
SB Live! 5.1
WD 120 GB HD w/ 8 mb cache
Lite-On 40/12/48 CD-RW
Win 2K SP3
Logi MX500 optical mouse
Case: Kingwin KT-436
PSU: Enermax Whisper EG365P-VE(FC) 350W
I did install DX9 and the latest nvidia det and soundblaster drivers.
One other thing - the EAX option on the SC audio settings is for EAX HD. I know my SB Live! 5.1 supports EAX, but I didn't see anything in the documentation about HD - is that only on Audigy and above? Twice I've gotten a horrible, loud static sound that doesn't stop until I close the game, but for the most part it sounds fine. Should I disable EAX HD in the settings?
Thanks in advance for any suggestions!
