if at best you got the vid card g210 NVidia it only supports up to shadier model 4.1

and then if you just use the onboard only is good to shadier model 3.0

Microsoft® DirectX® 9.0 Shader Model 3.0 Support
Ensures top-notch compatibility and performance for all DirectX 9.0 applications, including Shader Model 3.0 titles...
Shader Model 5.1 is functionally very similar to Shader Model 5, the main change is more flexibility in resource selection by allowing indexing of arrays of descriptors from within a shader.

looks like sm 6 may be needed soon?

but all the old shader codes should be built in to and part of the new revisions for compatibility sake and a non issue

so you need new up to date stuff to support the game with shader model 5.0 or higher

this is a hardware limitation and can not be fixed you would need a new vid card with shader model 5.0 or above

something like this may work [for example]

''Graphics Features''

OpenCL:

thing is its a hp and no guarantee any aftermarket or new vid card will work in it out side of what HP allows

you do these upgrades all at your own risk


as you may can see from HP forums as this

I don't know what to tell you no that but good luck
 
Solution
correct thing is finding a compatible card that will work on that HP with its proprietary board and proprietary bios .

that can be real funny with them

something like this would be at best I would risk to try
