Need help with frame-rate issue!

Hi, I recently upgraded from a nVidia 7900GTX to an Radeon HD 6670 GDDR5 graphics card and I was having some frame-rate issues with the Radeon that I did not have on the 7900.

While I can actually play some games that I couldn't before with the new card, iv'e noticed a frustrating loss of FPS in Diablo 3 for example.. I see some cool looking new special effects with the Radeon that I didn't before (which is cool).. but it seems to be reducing my frame rate uncomfortably.

I was wondering why the performance took a hit with a supposed upgrade to my graphics card. Iv'e reduced all the special effect settings to minimum (which I didn't have to do with the old card) and lowered the resolution.. as well as using the Catalyst Control Center to lower the settings to increase performance.

Has anyone else experienced what feels like a "downgrade" with an upgraded graphics card and is there options or settings that I can use to optimize my graphic cards performance?

  1. Is it just in Diablo 3?, Is it freezing then continuing? and also the catalyst manager is pretty crappy i would consider downloading "msi afterburner" and see what your mem clock and shader are set to.
  2. It's not just Diablo 3, it really seems like particle effects in all the games I play now really slow down.. not so much freeze. I just installed MSI Afterburner, I see that my memory clock is at 1000mhz and core clock is 800mhz, i'm not sure where to find the shader option on this.. ill tinker til i find it. This is the exact graphics card I have , maybe there's something that can help.
  3. Another thing i'm really curious about is the core clock CPU-Z says my core speed is around 1900-1993mhz which doesn't seem right. I always figured it was supposed to be like 800ish or something, I don't think iv'e altered anything that would effect that.
  4. Was really hoping to have an idea or solution by now on this forum.. does anyone know of another website or forum that specializes in graphics card issues?
  5. uninstall all the drivers that you currently have, get the latest and use stock speeds..if the problem persist..rma it!
