Is there another way to increase speed con Htmlviewer?

Hi team.

In windows platform, i have an Htmlviewer in Native Renderer mode, cuz i cant use webkit cuz the plugins that im using.
I tried with a solution that was in this forum, it talks about use a registry hack to force the using of GPU to render websites.

When i do that. Now i dont have scrambled screen anymore, but its terribly sloooooow.
In comparison with Webkit mode.

Someone already found a solution?

Did you also use FEATURE_BROWSER_EMULATION registry as well? If not, you may have the IE7 renderer.
