Hello , we're playing the modpack since few weeks we updated to 6.3 last week. Since the 6.3 performance seems to be bad , when i'm near a spawner or anything related with entities/block entities i get severe fps drops 140 fps with shaders > to 45 fps , even without 280fps > 110 fps when i render entities , did somebody experiencing the same ? 14Go ram allocated :)
