l0rdtr3k: I've started to play BG1 and I started to have some framerate problems.I tried to tweek with the graphics and only got worse what should I do?
You mean that the game played fine but started to have problems recently?
If this happens only in outdoor areas (with water) turn off Ambient Sounds under game options.
If not - please post some more info: your PC specs (esp. OS, GPU, drivers), mods (if any), current graphic configuration, what exactly have you tried and how it get worse.
And try to switch to windowed mode to see if there is any change.
