AMD Cat 15.3 beta 3 @ 7970 @ FAH

[DarkFoss]

Just a heads up the new beta with the opencl 2.0 driver still messes up folding on my gcn 1.0 cards. Workaround for the 14.12 omega seems to work, will update in a few hours.
*edit Workaround is fine holding a steady TPF of 2:51 on Project 9201 on both GPU's. I filled out an issue report survey with AMD for what it's worth.

Was wondering this myself... so all newer cards from AMD still suffer a folding hit with the new drivers? Boo, hope to see that improved soon. Thanks for filling out the issue report with AMD!

Hi DarkFoss, maybe you can test the new FahCore_18 beta, if the performance hit also exists with this new gpu core
I tried it with my AMD R9 280 and - as before - no performance hit for my card, so i can't tell...

Hi foldy,
Sorry for the delay had some rl issues pop up. Anyways I tried it tonite changed the flag from advanced to beta and got a couple of FahCore_18 betas. The bug is still there with GCN 1.0.

As you can see a 4 min difference in TPF I suspect it will only stretch as time goes on. Back to the modded driver for me

[foldy]

This is bad news. Maybe you can file a bug report to AMD for driver 15.3 beta, but i don't know if it will help...

modded driver?

Is that documented somewhere? If so, I missed it.

Hi foldy , I already did for what it's worth.
