Okay here goes, I have been dealing with clouds performance on my computer for a while now, It does not matter what resolution what format or what type of clouds I use When I am in super AA mode via catalyst controller settings My frames per second drops when clouds are on 3d mode, I get 16 to 18 frames per second when clouds are up at 20 percent or 10 percent on 3D

 

When I disable super AA mode in the catalyst controller I can set the clouds to whatever I want and I get really good frames per second But then the shimmering starts, Almost as if having the AA settings in full screen mode is not kicking in.

 

Bottom line,

Super AA - AA in game settings = great looks but bad cloud performance when set to detail and 3d mode.

AA- Super AA = great performance (No FPS drop) but horrible shimmering

 

I know setting the Mip bar within the game will help reduce the shimmering but makes the game look to blurry from far away.

 

If only I can get the clouds to work as they do with the Super AA mode enabled that would work extremely well.

 

Any ideas on how I can resolve this issue?

ATI Radeon HD 6750 1GB Ram

I trust you do have AA switched off in FS9? Check your cloud textures to make sure they are mip mapped and do not have missing alpha channels. (performance killers) If you have mips set in game and there are none in the textures your system kills time therefore performance to deal with that. Missing alphas are a error as seen by FS9 and likewise kills performance dealing with that. That applies no matter what brand of GPU you use. If those two issues do not exist then I would say it may perhaps be driver related - some simply work better than others when it comes to FS9. That said, I must admit I have no knowledge whatsoever about ATI products!

 

I hope this helps a little at least.

I don't think you'll be able to pull it off, sorry to say.

 

Last I messed with SSAA on my old rig, I had forced crossfire running via RadeonPro and would see 70%-80% GPU usage on both cards with 8xSSAA selected in heavy cloud cover.

 

That was with a pair of 6950s.

 

SSAA is wonderful, but very expensive performance-wise. I just don't think your card can pull it off with reasonable performance in heavy cloud. Best to stick with 8x/8xEQ, MSAA or maybe 16x/16xEQ MSAA if you can manage it.

Thanks for the info guy's, I do have the AA disabled within the game, and I have Super AA enabled Irgun my simulator alibg withe 4x AA the game plays well when the clouds are in simple mode and the graphics are great but when the clouds are set to detailed mode with set to 20 percent it's a bit stuttery when getting into the heavier clouds.

 

When the super AA is disabled the performance is great even with the clouds set to higher settings, but the shimmering effect takes effect with or without AA enabled within the game. I'm guessing that's just the ATI drivers and windows 7 64bit. I'm using Pablo Diaz hd clods 512x512
