hahahaha what? the flex is 100% client side, LL trees don't effect the server cache clear will only make you lag more (by downloading all the images over again, it gives a false performance increase (when images are loading, they're tiny grey textures, so it will perform better because there is less in the scene for a few moments)) client reinstalls normaly don't do anything because there is nothing that changes in your client folder driver updates on the other hand are normaly a very good thing to do! I know what your saying Moy but when I manually delete shit from my cache folder I get a pretty drastic performance increase for a good few days then it slowly dies on me as the cache builds up.
