Ulillillia, me too.

I get ~64 fps in window mode. I didnt notice it till your post, and tried it
myself.

I create a large hollow cube in wed and, save it as "test.wmb", and use this as
the only script;

Code:

---

var video_mode = 6;
function main(){ level_load("test.wmb");}

---

The crazy thing is, that in this most simple level, the fps cycles from 75 to
63 about every second.

I use f11 to see the fps. It flashes 75 and spins down to 64 within the space
of ~1/2 second, remains at 64 for ~ 1/2 second then drops to 63 for a frame or
two before repeating. Using triple buffer makes no difference at all.

This happens with 6.31 and the latest build. I remember getting much higher fps
than this in the past in window mode, so I am wondering if maybe it is an
graphics driver issue?

My machine is a 3.0 ghz pentium with 2gb sdram and a geforce fx 5600 256 ram.
So I believe I should be getting much higher fps in window mode in an empty
block with the most minimum script!
