The AMD Driver Thread

@AMDMatt - Hi Matt.
I know AMD stopped supporting older generation GPU's, but do you know if they intend to patch the Meltdown and specter bugs for older card?
I got a HD 6450 still in service, which I use for my workstation PC.

Good question - I've got a HD 6850 hanging around that's still serviceable.
Radeon GPU architectures do not use speculative execution and are not susceptible to these threats.
Soldato
To be fair most assumed that's why they released drivers too when in fact neither are vulnerable to the bugs.
Soldato
It was to mitigate the the CPU issues.

Thanks Matt.

It's not about the GPU being vulnerable - it's the fact that compiled applications that are executed on the CPU may feature sequences of instructions that can be exploited. Drivers are code executed on the CPU and so are potentially subject to Spectre Variant 2. There are many other applications that need to be recompiled and re-released to address this.
Soldato
So where is the AMD patch?
I know how this conversation will go.
Your gonna say AMD GPU's don't use speculative execution.
Sure. But I've just read nor does Nvidia.
So... Where is the AMD GPU driver patch?
You get the point I'm trying to make I hope. If Nvidia released a GPU driver to help mitigate cpu vulnerabilities where they don't use speculative execution either, then where is the AMD drivers to help mitigate this issue?

Spectre is less easy to exploit than Meltdown, so while I'd like to see it sooner rather than later, it's not really much good if it hasn't had enough testing and turns out to break things badly enough that it has to be rolled back. The various patches for MeltSpec have already encountered problems with particular configurations of system, so it may be non-trivial to make the necessary changes. Some can get away with just a recompile; others may find other areas of vulnerability that cannot be fixed by the compiler or otherwise run into an unacceptable performance hit and need a different approach. I get the impression that AMD are somewhat under-resourced in driver development capability.

Matt, Have you got any idea when we'll get a working Adrenalin driver mate?
It's gone a bit weird on AMD's driver download page, They moved Adrenalin off the main page and released the one with the DX9 fix but now it's back on the main download page but it's the borked one again, ie: Adrenalin 17.12.2.
When it's ready Nasha, no firm date as usual.
17.12.2 should be in the normal location, the 18.1.1 Alpha driver will be linked separately as its just a hotfix to patch that DX9 issue.
Permabanned
Fair enough,
The 17.12.2 driver is the bugged driver though, Originally they completely moved all versions of Adrenalin off the main download page and put the 17.11.4 driver back up so it's odd that they've put the bugged version back on the main driver download page when the 18 Alpha driver is rightly not on it, it's weird because the 18 alpha driver is the adrenalin 17.12.2 driver with a fix for the dx9 issue but no fixes for any of the other issues which are numerous.

only if you tell it to install it.
i did upgrade a few days ago bud and i've literally only just noticed its missing as i went to use it. i just assumed it woulda been in this package no?
A dare say it depends on whether their driver/compiler uses or is effected by the fixes on CPU side. Only AMD can say tbh.

Anyone here with VEGA play Forza 3 with latest amd drivers?
Any one experimented more with enhanced sync?
Unsure what I find best yet....
1. Capping fps to 60/120
2. not capping at all (which works best especially if above 60/120 fps all the time, however, fan noise is rather excessive then as well as temps)
3. using open gl buffering or not..... (seems to work best when not getting close to 60/120 fps
