Stuttering frame rate in 1.992 and 1.993

[Karnak]

While flying in v1.992 and v1.993 I am getting extremely frequent stuttering in the frame rate.  It will be reporting a frame rate of 45fps and every so often it will stop on a frame for half a second, or sometimes do a series of stutter stops of a tenth of a second each.

This seems more frequent when I look around, but also occurs when just looking forwards.

Im getting the same thing while flying /moving a stutter of fps
along with still seeing the triangles poping up in the screen for several frames

Fps hits the hi teens now and then when really busy
normally runs 28-35  peak 60  ,  90 looking up

I have pretty decent looking trees and grass  

the cv's become sort of transparent in there shading though
(see thru decks , bad water imilation ect here )

this is just the start , i have alot more testing to do yet .

Reposted from another thread since it fits here..

With 993, now getting major lags in display. Same as before... display hiccups, or stops for a brief moment. Now happening more frequently than previous versions.

When looking back in Spit, seat rivets are flashing/blinking.

With screen flashing, now see a noticable drop in frame rate. If at 45fps, when screen flashes/pauses it drops to 40fps and recovers to 45fps.
