I have an old MacBook Pro with 2GB RAM and the Core2Duo chip. Lion 10.7.5 is installed. I'm using it as an HTPC connected to my 65" TV via a DVDI to HDMI adapter and an optical cable going to my amp. This is working great for movies in plex. High bitrate 1080p movies work perfect. Netflix is a different story. I get bad stuttering during fast scenes. 1080p is almost unusable. 720p is at least watchable but isn't perfect.
I've tried using firefox, chrome, kylo and safari. They all perform the same way with netflix.
Is this expected for my hardware or should I consider doing a wipe and install 10.6?
