Kesshi Posted January 15, 2016 Share Posted January 15, 2016 One of our customers complains that our web-application is unusable in IE 11. On my desktop system at work everything is fine so i made some tests at home on my Windows 10 notebook. I used this demo to test the performance in different browsers: http://www.babylonjs.com/Demos/SSAO/ Here are the results: Chrome - 30 fps Edge - 29 fps Firefox - 12 fps IE 11 - 5 fps As you can see it runs smooth on Chrome and Edge. Firefox is slow but still usable. IE 11 is very slow which is also the problem in our application. I noticed that Chrome uses only 17% of the CPU while running the demo but IE 11 uses 99% of the CPU and the fan in my notebook is going crazy Is this a known issue? Can it be solved in some way? ... or is IE 11 really that bad? Quote Link to comment Share on other sites More sharing options...
Temechon Posted January 15, 2016 Share Posted January 15, 2016 IE11 webgl support is really bad, it's a fact. But try to check if gpu rendered is enabled (in IE options), and you're not using software rendering. Quote Link to comment Share on other sites More sharing options...

Kesshi Posted January 15, 2016 Author Share Posted January 15, 2016 Ok i think i know the reason. IE 11 doesn't seem to like my graphics card and uses the software renderer (Microsoft Basic Render Driver) as a fallback. Someone know if it is possible to force IE to use the hardware? Maybe an update to the graphic driver would help but i think there are no new drivers for my "old" notebook. Quote Link to comment Share on other sites More sharing options...
GameMonetize Posted January 16, 2016 Share Posted January 16, 2016 Absolutely...I was about to tell you to check the console to see if the software renderer was not used Quote Link to comment Share on other sites More sharing options...
Kesshi Posted January 16, 2016 Author Share Posted January 16, 2016 The strange thing is that there is nothing in the console about the software renderer. I used http://webglreport.com/ to check which renderer is used. Quote Link to comment Share on other sites More sharing options...
