I was able to run the game about 15 minutes before it stopped and uninstalled. I followed the directions that were listed and submitted the report
I am having this same issue on a Lenovo Chromebook Duet 3.
Not fixed
Effects 1.19.41.01
I am running 1.7.4 on an AMD Phenom II x3, with about 4 gigs of ram with no real lag issues until 1.7 came out.
I was getting high cpu usage even when no one was on (40 to 70% usage) after turning off the GUI interface it now sits at 4-8% when no one is on. This was the only thing I changed.
so the GUI is messed up somehow.
PS I was not getting high RAM issues so that might be a separate issue/issues
when view distance is over 8 is when I get the lag
I run a small server, and when no one is on the server is eating about 70% of my processor. this was not the issue before 1.7.2, when I was running 1.6.4 it idled under 10%
I have also had this issue in 1.47, i was able to let people connect by going into cmd and typing ipconfig, that gave me my ip, and then used the port number from minecraft to allow me to connect, so it looked something like this xxx.xxx.xxx.xxx:xxxx
Seems to be fixed in 1.20
