Stuttering still over 3 years! Any help?

[AstroCat]

I'll try and make this quick.

When IL2 came out it stuttered and we tried everything but nothing worked so I gave up on the game.
I came back in 2005 and tried everything on multiple systems but with HardwareShaders=1 enabled it always stuttered so I put the game aside.
Now, in 2009 I've come back and it still stutters with HardwareShaders=1 enabled!

All these different systems and configurations. Hundreds of tweaks of every kind, countless hours spent but still it doesn't work.

IL2 is the best WW2 sim out there, I really enjoy the game but the terrible stuttering when using water 1/2/3/4 just kills it for me. The stuttering is worse when the land meets the water. It is the same as it has always been on every system I've ever tried. If I turn off HardwareShaders=1 it doesn't stutter and if I turn it on it does. Oh, you can put water at 0, and it does help some and even water=1 is ok, but still stutters some, but really the goal has always been water=3/4 using the shaders.

Is there any help for this, some unknown trick I've missed through all these years? Or have people just done the acceptance dance that no matter what water 2, 3 and 4 stutter and that is just the way it is?

Thank you for the help! I just wanted to try one more time to fix this issue.
