Core 18 v4 (Windows/Linux)

[mpharrigan]

Hi all,
We're rolling out a new version of Core 18 (GPU Core) for Linux and Windows. This release fixes performance issues with Nvidia "Maxwell" GPUs as long as you have up to date Nvidia drivers. Specifically, 347.xx and above (Windows), and 346.xx and above (Linux). It still works with older driver versions, just with degraded performance on Maxwell. There are still performance issues on AMD GPUs, so the restriction on AMD gpus will be kept in place.

Right now, we will not configure the client to automatically download v4 if you have v3. To get v4, you must manually delete any earlier versions of the core. When we're sure there won't be any issues, we'll cause clients to automatically upgrade to this version. [Note for linux: since there isn't an earlier version of x18, you will get v4 automatically].

Currently, there are restrictions against Maxwell GPUs receiving core 18 assignments. We'll be relaxing those restrictions throughout this week.

Thanks!
