I noticed a slight delay in loading textures for one of the guns. Wonder what the performance will be like... ever tried running UE on toasters? anyway beta when?
That is something streaming textures does, though at some point we will likely have to force a cache on equipped models. I am running UE on what I would consider a toaster (9 year old PC) and it is doing just fine.
It also has been able to run on Hex's tablet so far (though not a lot of detail is in). UE is pretty scalable but with EC I'm not going to stress so much about supporting 5 year old pcs.
There wont be a beta for a while, maybe a pre-alpha is the first thing the public will get.
