WebGL Enhanced Graphics Troubleshooting
Part 1: Testing and/or disabling
You should be able to switch back an forth between the two types of graphics, Enhanced and Default. If you don't have that option, or if the map fails to load properly, check these steps.
First test of troubleshooting: visit this page:
and it should tell you that your browser supports WebGL and show you a spinning cube.
Second test: Visit this page:
https://browserleaks.com/webgl
And at about the 10th line, you should see this: "Major Performance Caveat False"
If that reads true, that will disable the enhanced graphics, so you want to see the word "False"
With the "Major Performance Caveat = True" result your game will only load in the default original graphics. If you believe that you are having a problem with the enhanced graphics loading the game properly, then the browserleaks site has a fair amount of information on it, including a section on enabling or disabling the WebGL in your browser.

If you disable the WebGL features of your browser this will ensure that you load the game in default graphics.
Fixing:
If your browser / computer failed the above tests, there are several things that you can check. These might also help if you experience some lag with the enhanced graphics, because as was mentioned earlier the expectation is that WebGL graphics will run faster, better, and smoother on all systems that are capable of running them.
1) Update your video card drivers. One player that I chatted with was not able to see the WebGL stuff on his 11 year old computer, even though that computer was top of the line at that point. I suggested to check the video card drivers, and they had not been updated in 11 years
I am pleased to report that with updated drivers for the video card that the webGL test links were indeed functional.
2) Verify that your browser has "Hardware Acceleration enabled". This is a fancy phrase for "Graphics card turned on"
In chrome you can go to this link: chrome
/settings/?search=acceleration and make sure the toggle is slid to the right. Other browsers have the same setting hidden somewhere. Firefox keeps moving it so I don't know which menu it is in now.

3) This doesn't apply to all computers, but we have found that some of the high end ones, including some alienware gaming laptops need to have some settings tweaked. Open your graphics card control panel and tell your graphics card that your browser (Firefox or Chrome) shall be opened with your graphics card. The default setting is that browsers are opened with the onboard graphics card of the i7, and possibly others.
I have a suspicion that steps 2 and 3 may accomplish the same things from a different direction, but they may not in all cases. You might check performance after each step and see how it works.
