November 26, 201312 yr 1) Tesselation factor - What does it actually control and is it best to just set to 'ultra'? Im having a hard time discerning what it actually does. 2) Setting resolution to 4096x4096? It looks as though all the ground tiles are still 1024x1024. Is there any need for this or just leave it at medium (1024x1024)? Edit - 3 questions! 3) LM devs said they support 1/2 refresh rate vsync. I dont see the option in the sim nor does the inspector option appear to work?

November 26, 201312 yr No 3) It is definetly there (I am not at my computer right now but look around in the Graphic section (on the right side of the card - a check-box and a pull-down-menue). No. 2) My understanding is that as long as the files a re smaller it doesn't matter anyway! No. 1) No idea. Could be the tessellation of the ground and/or water by the GPU!?

November 26, 201312 yr #3 - Triple Buffering = 1/2 refresh rate. And and explanation. Another method of triple buffering involves synchronizing with the monitor frame rate. Drawing is not done if both back buffers contain finished images that have not been displayed yet. This avoids wasting CPU drawing undisplayed images and also results in a more constant frame rate (smoother movement of moving objects), but with increased latency. This is the case when using triple buffering in DirectX, where a chain of 3 buffers are rendered and always displayed.

Here is an nVidia demonstration video showing what tessellation is, and how it works, using water and terrain as visual examples. The "tessellation factor" is a way of setting just how much tessellation to use: Fr. Bill AOPA Member: 07141481 AARP Member: 3209010556 Avsim Board of Directors | Avsim Forums Moderator
November 26, 201312 yr Author Thanks Bill.....very informative. Does setting it high or ultra have major FPS impact? Also, regarding vsync. Yes, I have a pull-down menu which simply states 'on or off' There is no 1/2 refresh rate option. To my knowledge, triple buffering does not equal 1/2 refresh rate vsync. Am I wrong then?

November 26, 201312 yr Maybe this can help?:- One thing to keep in mind is that the v-sync is adaptive. Assuming you have a 60hz monitor, enabling v-sync will lock your frame-rate to 60, 30, 20, 15, etc. If you enable v-sync and set your frame limiter to exactly 30 you will artificially introduce stutters by dropping to 20hz for any frame that runs long. I would try locking the frame-rate slightly above 30hz so that frames which run slightly long don't cause a stutter. Enabling triple buffering with the frame-rate locked about 10% higher than the desired refresh rate tends to give very smooth results. Zach Heylmun PREPAR3D Software Engineer
