Poorly Optimized Performance

Since the release of Minecraft 1.18, the performance on older computers such as PCs and Macs from 2012 to 2016 with dual core processors is slow, sluggish and very laggy making the game somewhat unplayable. Because these older computers ran Minecraft very smoothly back on Minecraft version 1.8 to around 1.15, then this means that Minecraft is a poorly optimized game on 1.18, 1.18.1 and 1.18.2. Please make this more optimized for our hardware and make it be able to use all CPU and GPU cores effectively so that the frame rate is better.
