Is there any way to disable the dynamic lighting effects?

[Ciderpress]

I play p99 on an old winxp machine, that for it's time was more than capable of running EQ smoothly (during pop). P99 runs fine most of the time, unless there are more than about 20 players around. The cumulative dynamic lighting (the thing that makes the entire EC tunnel look like an atomic bomb is going off in it), is absolutely awful on my GPU. Ditto for raids, or even scout rolls. FPS absolutely tanks and the temp goes up to max. This is ridiculous for a game this old. Yes the machine I play on is old, but this same machine ran live EQ perfectly fine through the PoP era. This problem is specific to P99.

I'm certain it's the dynamic lighting. Turning spell effects off, or clip plane down, or yada yada has absolutely no effect. This only happens when a large number of players holding powerful light sources all congregate together. Raiding is basically impossible because I'm averaging literally about 5fps in TOV during a big raid.

Please for the love of god tell me there is some way to disable these blinding lighting effects. I appreciated them when green first launched, and you could see little glows from people holding torches, but it's just ridiculous at a raid.
