If rendering tasks could be migrated to the GPU it would be  a very good thing (the game is still cpu rendered?), or just hardware utilization in general. On large modpacks, my framerate can go down to like 13, but my cpu and gpu will only be running at ~50%. If this could be optimized it would be great.

 

If the game is CPU rendered, could we at least have TESRs run on the gpu? This should make mods a lot less laggy

That's not how rendering works we cant just wave a wand and say 'here you go GPU is now doing it!'

1.8/1.9 do LARGE strides to move the rendering away from the CPU, but that's the #1 thing modders are bitching about because it means they have to adapt.

 

As it sits, we are not in the market of rewriting extensively large swafts of Minecraft. So no.If Mojang continues to change to better rendering we will encourage and make it easier on modders to move, but we don't dictate something this fundemental.
