distance objects flickering in crysis/warhead

hey guys, ok so i play crysis because i can finally run it at 40 fps and above with all settings on very high. so with that since i have a pretty small resolution, i need to use a good amount of AA. so if found that i can run crysis all very high with 8xQAA and keep my great frame rate of 40 or higher. but the issue im having i dont think is related to AA setting but i could be wrong. so in crysis i stand at any place where i can see far ahead (not like super far ahead but just far enough) and look at the objects in the distance and things like trees and bushes flicker, but when i come in close enough to the tree or bush it stops, but in the distance it flickers and its annoying because theres lots of vegetation in crysis.

i run SLI GTX 260-216 with a Q9300 @ 3.2GHz with 4GB OCZ SLI Ram oc'ed to make a fsb : dram ratio of 1:1. i have the latest 180 driver thats whql (i dont use beta's), my game is patched to the latest and game settings are all very high and 8xQAA. i play at a res of 1360x768 (just above 720p, i use HDTV as monitor and NVCP shows 1360x768 as native res). i use v-sync and triple buffering (cant stand tearing, it honestly give me a headache after about 10 mins). thanks for any help in advance.

FWIW, I had the same issue in Fallout 3 when I turned the draw distance down. When I turned everything back up to max, it all went away.

ok some more info, i had force v-sync on in the nvcp and i had v-sync on in the game. so i turned off the force v-sync in the nvcp and went into the game and it still had the flicker, so i then turned off/on the games v-sync and it went away. why would this cause it to go away?

ok never mind, when i quit and went back into crysis the flickering was there again. so if any knows why this is happening and could tell me how to fix it that would be great. thanks in advance

you don't need sli for that res, if you ask me you've brought your problems on yourself

alright thanks man, ill try re-installing the drivers for it.
