I think u used gsoft plugin ergo u change it to gsdx maybe that solves ur problem. but kind of pixel shader depends ur graphic card:
geforce 3,4,MXs/ATI 7000,7500,8500: pixel shader1.1
geforce FX5200-/ATI 9000,9200: pixel shader1.4
geforce FX 5600-5950/ATI9550,9600,9800 : pixel shader 2.0
and better
ixel shader 3.0
geforce 3,4,MXs/ATI 7000,7500,8500: pixel shader1.1
geforce FX5200-/ATI 9000,9200: pixel shader1.4
geforce FX 5600-5950/ATI9550,9600,9800 : pixel shader 2.0
and better
