Hey Tom, yeah this 'fix' (albeit not perfect) is only for SP2 clouds, they worked perfectly in SP1 so there's no need to try it with that. The SP1 cloud shader is *very* different from the SP2 one.Cheers,-mike

Thanks for this fix - seems to work fine on Vista 32, DX9.One thing I noticed is that my GT8000 graphics card is pushed much harder than before - the core temperature goes higher and the tiny fan has to work *much* harder now when looking at clouds.Tom

This is indeed a great fix for flashing clouds - but I lose the wake behind the ships when I apply it... :-(Is the same shader used for both, maybe?Win XP Pro, FSX w. Accel.

Well I just checked the wakes on ships, and they're still working fine for me. The wakes shouldn't be related at all, they're just an extrusion effect. All I can say is don't be surprised at seeing little scenery oddities from time to time with this change. One guy reported seeing a house doing circuits at an airport after trying this, so who knows. :)Myself I've only seen some problems with LODs on port cranes since the change, but my FSX is so shredded from all the testing I did to find a solution to the flashing that it could be anything causing that. As for the fan spin up issue, might be the 171.16 drivers? When I tried those on my 8800 ultra my fan went crazy 90% of the time. However, whenever you have tons of cumulus out to the horizon and you're looking at them edge on your videocard will have to work harder, that's a lot of alpha polys to sort out.Cheers,

such a connection is highly unlikely, you might want to check your card for other issues.

Who knows, indeed.. ;-)

ok i changed the entry in swarmcloud cfg and when to my appdata but no folder for shaders in the fsx folder anyone else missing this? also did a folder search and the only one to come up is the shadershlsl in the main fsx program file
