I have a hd5470 in which my pc software died a while ago, i reinstalled a bootled windows 7 copy onto my computer but cannot see a different in fps with or without drivers it stays the same, I used to see a different with the ture version of windows 7 but now I don't . I've tried and installed various amd drivers but I see no difference , would it be due to the bootleg windows 7 version or not ? P.s I have set the ccc settings to optimal performance.
