Last night, I changed the "Default" aperture size in my bios from 64 to 128 and ran the Mad Onion 2001 and 2003 tests. Both improved by around 1500 points plus some of the choppy video in FS2004 was reduced in high demand scenery files. I do not know if moving up to the final setting of 256 would help any more or not. My system is a P4 @ 2.8GHz with a 800MHz fsb and 1 Gb of DDR 400 MHz ram, and all running through a ATI 9800 Pro.From what I can tell right now, all I did was to allow the system to "Breath" easier and or let the data flow even faster. Anyone else have similar experience with this AGP settings?Terry

This would be a quick and easy fix. Anyone else have thoughts on this? Would it work on older cards, specifically a Geforce 3 TI 200?rgds,billg

It seems the AGP aperature topic swings like a pendulum in the FS series. There were lengthy threads about reducing the aperature to a minimal setting or even disabling it completely to improve FPS in FS2002. I noticed no difference but the logic for reducing it made sense to me so I reduced mine to 16 meg. Common wisdom was also to disable AGP Fast Writes because it was supposed to be useless and could create stability problems. If I'm not mistaken, Riva Tuner disables Fast Writes after it is installed. With FS2004 I had some stuttering and an occasional lockup problem within the sim that I couldn't eliminate. Resetting my AGP aperature to 128 and enabling Fast Writes has cured both issues with no apparent system stability problems. It also eliminated some stuttering I had in Fly II that I thought was scenery related.
