Hi, Stoyan from Coherent Labs here. My impressions of CEF are very good. They manage to keep it very close to the chromium HEAD, which is great. The only technical downside of CEF is the imperfect GPU acceleration. In many cases however the architecture of chromium itself is a hindrance. Their processes hog memory like crazy and introduce perceivable lag. We had to write a complete new product to solve the issue for games.
