I searched the forums for anything to do with Anisotropic Filtering in FSX and didn't find anything about it regarding the context of my post.Here are my observations. I recently purchased a new video card and set it to 8xAA and 16xAF. My performance in FSX was terrific, especially the smooth, silky feel. While rummaging through the settings inside FSX I noticed that I had filtering set to "anisotropic". Thinking back to FS9.1 where we disabled AA inside the sim when we had AA enabled on the video card I thought the same might now apply to AF in FSX. When I disable AF in FSX my FPS jumped about 70%. I couldn't believe it so I switched AF on and off a couple times inside FSX to verify the performance impact. Give it a shot and let me know if you experience the same thing. There was absolutely NO performance degradation with AF disabled inside FSX.

Adam Szofran talked about this setting at the AVSIM convention. When the FSX setting is "Anisotropic", FSX will configure the video card for 8xAF provided that your driver is set to "let the application choose". If you configure a specific AF setting in your video driver config, the FSX setting is ignored.RegardsRich

don't usually post but was at the conference too! I did the same as you (7800 Gtx 256) plus I have since put the sim on its own drive sata 7200 with swaap file going to its own drive and flying the opening default flight was getting nearly 70 fps ave at dusk and was near 30 at jfk at night with the 737 sliders set as outlined by adam at the conference. before was 15-20 fps and 8-14 at jfk. go figure! 100 % default traffic 5% boats and cars home built AMD 4800 x 2 2 gb Corsair ram samsung hard drives....o-clocked 7800 gtx using coolbits otherwise stock using 91.47 drivers

Hello,"When I disable AF in FSX my FPS jumped about 70%. I couldn't believe it so I switched AF on and off a couple times inside FSX to verify the performance impact"Where can you in FSX disable AF ? when I look at the Settings-Display Graphics I only find Anti-aliasing option.Thanks in advance.

Ok after posting I found that my sliders were set to low with no autogen, once this was corrected to what i indicated the default scenery from the ultralight was 35-46 fps. anyway i guess this shows the scalability of the sim even it its beta versionbye Gregg D
