Thanx GeneralPlot to answer!
I use gsdx0.9 I got P4 2.6 ghz and mobility radeon 9000 1GB ram, but when I test the plugin it tells me ok on pixel shader, but error separate alpha blend, source blend factor, and error destination blend factor. The old gsdx worked with my pc If I ignore this and try to launch a game I got a popup telling that My pc support pixel shader 1.4 and I selected 2.0....
Sorry where I selected?

there's no option to selected it
Thanx in advance
