Hey All, I installed KOTOR2 on my computer for another run through, and I seem to be having issues with my graphics. I have a ATI x1550. I got through the first section flawlessly on relatively high settings (1024x768) high detail, shadows, all of the above, etc. No AA. Then, after I got to Telos, I started running into issues. As soon as I landed on the planet, it became laggy. Or choppy, to say the least. It's like watching a slide show. So, I lowered a setting or two (texture detail, turned off shadows, etc) and it went back to working. Then I zone into that stupid long hallway and I'm choppy again...I lower some more settings and it works for a bit, until I zone again...Then, here I am at lowest settings, laggy again. It's driving me nuts. Also, I noticed that the smoke on the intro around the sith lord guy lags. I did the requirement test, and I passed everything by at least 1-2 green bars. Also, I downloaded the most recent drivers. EDIT: some more info...I have a gig of ram, and running XP Also...changing the level of detail (Either up or down) seems to make it better but that is not acceptable to me to have to do everytime I zone.
