If you want you can send me the screenshots and I'll post it together with your complete article at our articles section.

I'll get on it, 2-4 would seem adequate, I had 2 on our hotline server, but I need to get two shots en which the comparisons have a bigger difference, I'll probably have a few by the end of today, I'll email them around 9 central (U.S.).

i once activated mip-mapping without taking notice........

i got 5frames!!! horrible!!!!! impossible to play!!!!
i needed 2hours to found out, that it was mip-mapping which caused the low performance.....

Thanks for the screenshots spider. Well personally I think the game looks much better without mipmapping. Mipmapping makes everything blurry and it seems that it has problems to render some textures properly. Spider look at your Frostbite mipmap picture - the fences are totaly screwed.

Anyway I gonna post your article soon.

Me too.  I tried it with mip-mapping on to see if it improved anything.  To my horror it made the game almost impossible to play.  I was utterly disgusted with the performance I was now recieveing.  I mean my computer is no slouch when it comes to performance.  I am running a Dual 867 DDR and to be honest my framrate was pretty good.  But when i turned mip-mapping on my performance went to shit and the graphics were actually worse.  To be honest Spider I like being able to see more detail in the pictures, and by switching it as u suggested it made the comp look like serious shit.  I am glad though that it works for you, but for my comp I would never use this thing.

did you try changing the value?
0.5000 to eg. 0.2000

Yes, unfortuantely I went exactly by the written instructions that were left on the forum to give it a shot.  Unfortunately it made the game way too laggy for me.  That dosent mean it wont help other people, but on my higher end machine I would have to say that I didnt see any improvement.  In fact it was much worse.  Srry

Results may vary, even with the lower LOD, mip maping does not like map textures set on high?the rest seem to be fine though?

My results were the exact opposite. Mip-mapping increased my framerate from a 35-40 average to 40-48. (Spikes of 61 here and there, hehe)

Setting the level of detail bias to 0.2 seems to work on my machine, generally, ghost recon does not like map textures set to high with mip maping on?and if your system is lower than a 600mhz iMac g3, then you should have character textures on medium as well.

hmm, well, I must say I am glad that it works for at least some people.  To be honest I didnt really need the tweaking anyway cause on good maps I get between 40-60fps, so that's kewl.  Although I guess maybe it seems to work better for lower end machines, which is kewl as well.  Far out

If you have a Radeon 9800 Pro and the latest drivers (4.1) then I would recommend turning off Mipmapping and use the 3D Overrides to turn on 16x Anisotropic Filtering.  The image quality difference is huge.  It's best seen in motion but I have some screenshots of Ghost Recon with various graphic option combinations of multi and super sampling FSAA, aniso tropic, mipmapping, etc.  I'd recommend downloading the images to disk, then opening the ones you want to compare and switch between them (command-~ in most apps running in 10.2).
