Thank you sir.. this looks a great solution but I want to convert my paintfx to polygon and this is not working when on polygon mesh..Turn down the stroke quality.
Yes I want to purchase a graphic card. does this work fine with it 'evga geforce gtx 560 superclocked 2048 mb'. I don't have a big budget right-now. As I want it to work good with both Maya and Mari. I haven't use mari yet just because of Graphic problem..Well you are also running on the i3's integrated GPU with no dedicated graphics memory which might be fine for browsing web pages or using word but not so much for running Maya.
Maya really requires a dedicated graphics card.
The GTX 500 series should work out for you. Many on the site (except me unfortunately) are using the geforce cards very successfully.
I apologize for sounded so sarcastic but it's inevitable that anyone trying to run a program like Maya on the native intel HD GPU will at some point have performance issues.
