not sure what "Still Lagging" means
To be honest Ben - this is a question for nVidia not Trimble - I probably have the same question and I am sure that we all leave Hardware Horsepower on the table in a variety of places but TBC just uses what it wants to and what is available.
I agree that you get into these controls and it is complete gobbledygook for most normal people - maybe extreme Gamers get it or programmers, but the average person just trying to get the most out of their Laptop it sure is not easy, If others out there have found a magic setting or button that makes a big difference to TBC specific performance in here I am sure many would like to see that / hear that - I think I will leave this one Open for anyone that wants to comment or offer advice.
Graphics Performance and Graphics Quality are different beasts - the Performance I assume is what you are looking to improve or speed up - that is very heavily dependent on the following parameters in TBC
1) The Type and Quantity of Data on Screen
2) Linestyles (Solid or other)
3) Text Styles (True Types are Slower than Stroked)
4) Points vs Point Clouds - Point Clouds are many times faster
5) Line Markings On / Off (Off is much Faster)
6) Point IDs, Elevations, Symbols On or Off - Off is much Faster
7) Geographic Limits and Elevation Limits of the Project (Large is slower)
8) Images / PDFs on Screen or Not - On is Slower
9) Number of Views that you have Open
10) Number of Screens you are running - if you run 3 Screens then you get 1/3 of the Graphics Memory assigned to each - so an 8GB Graphics Card just got cut back to 3x 2.7GB Graphics Cards - so if you are doing intensive work shut off the extra screens you dont need. Working on the Laptop Graphics Screen is faster than an external screen
11) Docking Station in the middle - These take away Graphics Power - working off your own Laptop Screen and undocked is faster
Having more Graphics Memory only helps if all the Graphics Memory is used up, but splitting to multiple screens burns up graphics Memory so thinking you have 2GB Card and using 3 Monitors will affect performance - try unpluiugging and running stand alone without Dock and External Monitors to see if it makes a difference on a file that you consider to be "Lagging". I see more issues with Data than I do with Hardware issues - cleaning / sorting data often makes a better project and faster project.
And all the above are going to most likely have more effect on TBC than any one setting in the nVdia Controller itself
If your screen is not the greatest Quality or you have the wrong driver installed (or no driver for that specific screen) then these will also have an effect on Quality - the nVidia settings again will have a lower impact than just this one thing, however if you play with nVidia Control Settings then you change the defaults (which are good settings typically) you can just as easily deteriorate your system adversely as improve it.
On Direct X - we support Direct X9 and higher in TBC - depends on the age of your machine and your graphics card whether Direct X 9,10,11 or OpenGL or Open GL2 will work the best with TBC - you may have to experiment to get the best solution. There is not a one size fits all answer to any of the above so that is what makes it hard to answer this type of question.
Maybe take a tour of the nVidia Website and see if they have forums where you can get help from nVidia Experts on this
