Undetectable GPU hack
Is it possible to hack the GPU driver for undetectable hacks.
e.g.
show the depth-buffer
map color to another
set alpha for all/some textures
have an extra camera e.g. top view in FPS
remove shadowmap
Anything is possible low level. Whether it is undetected or not is another question.
U probably refer to ring0..
If u are looking for that kind of private cheats,it wont be cheap.
