Example URL:
http://www.abcya.com/spanish_vocabulary.htm

Steps to reproduce the problem:
1. Review your test VM CPU baseline on the ESXi host using esxtop
2. In the Guest VM launch chrome and navigate to a website with multimedia demand. In our example we use www.abcya.com/spanish_vocabulary.htm
3. Review your test VM CPU utilization in esxtop. 

What is the expected behavior?
Following the steps you will notice the VM CPU utilization on the ESXi host maxes out. In our testing our baseline CPU was 3-5% and when we navigate to certain websites the CPU utilization jumps to 200%+

What went wrong?
CPU utilization shouldn't max out when accessing websites.

GpuProcessHostUIShim: 

I am looking to see if Google can offer any insight into tweaks that can be made to the Chrome browser to optimize it for a VDI environment. I posted this on the Chrome Support forum and Julian Pastarmov asked that I open this as a bug on crbug.com instead.

When monitoring our VDI sessions via esxtop we are noticing increased CPU utilization. We contacted VMware support and their engineering team is attributing the spikes to video rendering demand of websites. While I was aware that opening full screen 4k videos on youtube would trigger this behavior I wasn't expecting simple interactive games such as www.abcya.com/spanish_vocabulary.htm to cause the threads to spike to 200+%. This site has been used as an example since it is known to trigger the issue. 

Attached I have included screenshots showing VM CPU baseline around 4% sitting at desktop but when we launch chrome and navigate to the aforementioned site the VM CPU spikes to 200%+ . VMware engineering was able to replicate this behavior across different ESXi builds and hardware and is reporting that the increased utilization is a result of increased demand. 

During research I found sites that mention advanced settings in chrome://settings, chrome://flags, and chrome://gpu however none specific to VDI or how each would be beneficial. One guide http://superuser.com/questions/697567/how-to-reduce-google-chromes-cpu-usage mentions reducing CPU utilization by adjusting certain settings but the thread is a few years old and I know flags and settings are changed with each update.
