Some comments :
1. It would be important to make the system work with GPU's 1 GbRam because it is the one that most users have. You can reduce textures with any of the existing programs without losing quality as the "Optimizer Textures" or similar. ??
2. Currently, there are servers in 1.5.4 with access difficulties, I do not know the causes but the data transmission is saturated and there is no way in.
