Finishing WebGL Quest in IE11: rendering speed over chrome

Summary: IE11 started to support WebGL and worked very well, IE11 's WebGL renderer was more than 10 times times faster than canvas2d and found the same results on other WEBGL-enabled browsers, which would improve the performance of many games.

Microsoft's latest browser, IE11, started to support webgl--although it was based on OpenGL, the nemesis of Microsoft DirectX. Recently, Microsoft has promised to open up a lot of information about IE standards, suggesting that they are really serious about it. They put their commitment into practice, providing a true standard-based feature-the hope that this trend will continue.

About a year ago, Scirra had a review of IE10, and the results were not as good as it was imagined. So how does the new generation of IE11 behave? How will it contend with the new version of Chrome and Firefox?

The advantages of WEBGL with respect to canvas2d

For construct 2 games, ie support WebGL is pleasing. You can now use the WebGL shader effect, and IE11 is also compatible with the effect. In this way, construct 2 game images such as Rain demo will be more vivid.

What are the effects of WEBGL support for the IE11 construct 2 game? A renderer test was performed to measure the number of screen sprites that the browser can manage under 30FPS conditions (Link: WebGL test and canvas2d test). The test PC is equipped with a Windows 8.1 64-bit system with Intel Core i5-2500 (3.3 GHz) processor, 8GB memory, and nvidia GeForce GTX 660 graphics card.

The effect is very different! the IE11 WebGL renderer is more than 10 times times faster than the canvas2d . The same results were found on other WEBGL-enabled browsers. This will improve the performance of many games, and for mobile developers, they would very much like to see how WebGL will affect the game performance of Windows Phone 8 because the game performance of the mobile side is more important.

WebGL speed comparison of IE11, Chrome and Firefox

Surprisingly , in this test, IE11 defeated Chrome and firefox! this may be because IE11 uses a DirectX 11-based renderer and uses the newly optimized JavaScript engine. This is the first time to see IE scored a significant lead in Chrome and Firefox, hoping this score will enable Google and Mozilla to further improve browser performance. It will be a very good sign that the browser market is again in a healthy competitive state. Fortunately, the performance of each browser is excellent-I think only a small number of games can have more than 10000 screen sprites.

The last advantage of IE11 support for WebGL is in retro games. for games that use pixel graphics, it is important that you zoom in on the graphics to keep the game pixelated. The IE10 uses a fuzzy linear scale, which destroys the image sharpness. Because IE11 is capable of supporting WEBGL, the game is able to sample points and stay retro-inspired. IE11 can also support the canvas2d renderer, so you can choose any way. But IE11 uses the WebGL renderer by default, unless you turn it off (not recommended).

Full-screen API support

Other major new features of the desktop version of IE11 include support for full-screen APIs. This means that IE11 can meet the browser's goal of "full-screen motion requirements", such as IFrame ' d and other games can be run full-screen. This will be a very good extra feature in your game, especially for arcade mode games.

Support Windows App Store App

Perhaps to meet compatibility requirements, the Windows Store app is still using the IE10 engine. To use the IE11 engine that supports WEBGL, you must republish the game for Windows 8.1. You should also use construct 2 r147+ to export the game to Windows 8.1 and publish it using Visual Studio 2013.

Conclusion

Support for WEBGL is much more improved than IE10 support HTML5,IE11. For construct 2 games, IE11 support for renderer effects and performance improvements are valuable updates. In the test, the IE11 full screen support was excellent, surpassing Chrome and Firefox.
