I would like to know how can i activate directx features, i have every drive installed on my machine. why xp you may ask is because i get a huge fps bump on xp(arma2 dayz mod).
you cant, XP is no longer supported by MS, and DX hasnt been updated in a long time. Also, driver are no longer updated by AMD. You might try Linux with Wine, it might have better support and get you the FPS you are looking for.
not really sure how you managed to get any drivers installed for xp in the first place since that apu was never supported under xp at least according to amds website you could try inf modding the xp64 version of desktop catalyst 14.4 but it is has a very low chance of working since again no xp driver was ever released afaik for that apu.
I dont think that is a catalyst problem because on the xp64 bit folder the inf file have all richland gpu incluiding mine, the driver install with no problem.
Dxwebsetup is better, it updates all components to current version. https://www.microsoft.com/en-us/Download/confirmation.aspx?id=35
you could also try the catalyst 13.9 driver if you can find the xp64 version of it there are few drivers that are xp compatible unfortunately since xp support was dropped just about a year after that apu being released In the chance that it is the os install, i would reccomend installing the base version of xp64 without the service packs and try regular 32bit xp and see if anything changes if you haven't already.
