    Major frame rate issues with 15.3 and AMD Crimson in Fallout 4.

    jberry0410

      So been playing fallout 4 on Ultra with God rays at high and shadow distance at medium. 1080P resolution and been maintaining 50-60fps steady with 15.11 drivers. However today I downloaded the newest Crimson drivers that were listed at 15.30 and now I am having major FPS deviation in all locations, but most notable is indoor locations.

       

      It is not uncommon to go anywhere from 20-60fps and everywhere in between. This was not an issue with 15.11 and having reverted back to them I seem to be doing fine, is anyone else experiencing this issue with the new drivers and Fallout 4?

          Yess, i have the exact same problem. Fps drops/fluctuations are visible especially in indoor areas. The fluctuations are huge and annoying as hell.

          I tried everything from changing all Crimson setting to turning Fallout 4 v-sync off to doing a complete DDU uninstall and reinstall of Crimson drivers but

          nothing helped. Turning v-sync off didn't help at all.

           

          I've noticed my GPU isn't running at max clocks when playing Fallout 4. The GPU's core and mem clocks fluctuate wildly.

          I reverted back to 15.11.1 and it's working fine now.

           

          I was so happy for Crimson drivers (GTA V runs better than ever with Crimson) but this bug is too much because i play F4 a lot so i had to revert

          to 15.11.1.

           

          My system is:

          I7 2600k

          MSI R9 390 8Gb

          8Gb DDR3 RAM, 1600Mhz

            Hello,

             

            If I could offer any advice it would be to revert back to previous drivers as Crimson isn't too stable right now I'm afraid. I myself had to revert back to 15.7.1 major power consumption issues with the Fury X being capped to 600mhz core. I hope this helps.

              Use ClockBlocker. It's a program that some dude made and it fixes these downclocking problems with Crimson until AMD release fixed drivers. Most ppl use it i think because it works great. I use it and have no problems with Crimson.
