New Minecraft render/optimization

I'm so sad to tell minecraft gamers from this amazing commuinity that mojang has updated the 21w10a, you see, maybe you don't understand the bad thing at all... now, if you have an old computer/laptop you cannot play new versions anymore... now you can just play untill the 21w09a

Why?

because of minecraft new render, you basically know that minecraft is not the most optimizated game... how did they repair that? making a new way to render that excluide all minecraft players that plays on old computers

Solutions?

I think minecraft needs to add other solucions, it's so unfair you can't play minecraft anymore, first of all I gues mojang prefer to update than optimize, why they can't just optimize the game like optifine? they do not exclude player and they optimize way better than Minecraft do... I think the best solution is just to optimize like optifine and maybe better knowing that mojang is part of MICROSOFT, one of the biggest companies nowadays...

now?

the better than mojang can do now is to let minecraft people with old laptops to play knowing that the game might render wrong, you can't just ignore a porcentage of player for new updates, that is and will be unfair...
