Graal v4 seems to lag on certain parts of certain levels. I know I'm being vague, but I don't know the exact problem. I've had this problem ever since the public release of v4. It occurs in certain levels like:
N-Pulse: level3.graal, cloud_j08.nw
Maloria: mainhouse.nw
The lag occurs only on certain parts of the level. Coordinates above 20-y seem to be really laggy in level3.graal on N-Pulse. The upper half of cloud_j08.nw also seems to be really laggy. mainhouse.nw on Maloria is laggy in the middle-bottom half of the level. In the process of trying to find a solution, I've removed all the weapon npcs in my attributes as well as flags, yet it was still laggy.
I'm using a Nvidia gfx card with the most up-to-date driver as well as directx. i'm running a winxp platform.
Graal console shows no error:
