dunno if anyone here has tried this - from the Avsim FSX forum board

Be aware of this issue,
It's fx_skidmark.fx, located inside the main FSX effects folder.
A file called skidmark cant be any good when it isn't actually providing any visible effects.
Trashed it and now, no more fps drops, with hardbraking, on dry or wet runways.
Problem solved, for me at least.
If you feel you have no need for skidmarks(are they actually rendered?) , and are experiencing this problem as well, by all means get rid of the file. See if it helps you.BIGSKY
Heywooood : Removing the skidmark file, combined with the usage of the external FPS limiter, brought me FSX smoothness at last.
I cannot stress this enough - SMOOTHNESS - like I have with Rise of Flight..absolutely ZERO chop now (except for ATC caused - when will we ever find a cure for that?)
stable FPS at 28-30 virtually everywhere with virtually every 3D model...seriously :Heywooood

in the main FSX folder - in the Effects folder - copy and save elsewhere - then delete from the Effects folder this "fx_skidmark.fx" file
once done - you might notice drastically smoother panning in all views in FSX...especially if you noticed some stickiness in the camera pan while taxiing or taking off / landing
this effect file - as BIGSKY said - doesn't seem to render anything! it just causes these stutters - once removed you should be able to pan around without ANY lag or stutter
- keep in mind - the more AI you use, the more you will notice improvement as (I believe) this effect is activated by ALL aircraft, not just the users aircraft.
make sure you save the effect somewhere (desktop) while you test FSX without it
