With Bojote's Shader 3.0 Mod, 2x water effects should not have that big of an impact on frames. Especially when set to low or medium. Regardless of the 3.0 Mod, 2x water at medium or low shouldn't have a big impact on anything >GTX260.

Not an expert but heard a lot of conflicting stories about that mod.

For me it was about 5% upwards, but quite different animation, I would say original looks better. 2.0 Low is a good mode IMO.

I honestly can't tell a difference with the looks.

Well i will give it a try. Why? Because the advise you gave me on antivirus & MSE in another thread works. My max temps during FSX sessions have dropped 4deg. i assume due to lack of background activity. Bit off topic, but thought i would mention. Thanks Zach.

From the MSDN blog: Visual Results for the Various Detail Settings Instead of writing a long paragraph on this, I think a picture is worth a thousand words. I have captured a snapshot of the same scene using the various 2.x water settings. In the caption below the image I indicate what is rendered inside the reflection map and I've also turned on a debut feature which shows the content of the reflection map in the top-left corner. I will not go into the details of where all the performance goes, but you can likely extrapolate from the amount of detail in each map that the Max setting is going to cost LOTS MORE than the Low setting. Water 2.X Max - All is rendered, equivalent to rendering the whole scene twice with the exception of a few optimizations which take advantage of the autogen and batching LOD system to reduce the overall number of draw calls. Water 2.X High - Only the aircraft, full sky (with clouds), terrain and non-autogen scenery is rendered. Water 2.X Med - Only the aircraft, full sky (with clouds) and non-autogen scenery is rendered. Water 2.X Low - Only the aircraft and sky (without clouds) is rendered.

Cool but wheres the pictures ?

Oh! I meant between using Shader 3.0 mod and default. (Which would make sense.) I can definitely see a difference between each FSX setting!

Glad to hear it!

They are not even on the MSDN website any more. Open FSX and check yourself. Differences are clearly visible.

Have you followed the performance guidelines in the introduction document, and have you tried a fresh fsx.cfg file through ******* Altuve's config tweak tool?

******* Altuve's config tweak tool? Where I can download that?
