2xSai is pretty much an algorithm to double the texture size and then apply a smooth filter to it. In theory, as there is no new data added for the texture, there is no real enhancement for the texture.
It increases the texture size, and makes each point bolder, could make different filter effects from linear or bilinear filters, while the linear and bilinear filters are doing good jobs to smooth the texture.
Do we really want to make the texture bolder instead of smoother? For 2D games, it might work because 2D game emulators can not enhance their image quality by any other means anyway. But for 3D N64 games, I wonder if this is a good way to do. By doing that, the texture and color become heavier, but less real. Maybe things such as text fonts, 2D logos do not need to be as real as possible, but large textures such as sky, wall, ground, fires should be as real as possible. I guess fire effects will look bad by using 2xSai.
I could have some wrong understanding about 2xSai or similar filters, can anyone explain it to me if you happen to know it better?
Btw, if your PC has too much computation power, bilinear filter could be a better choice than 2xSai.
