Radeon Mobile HD driver bugs under windows 8


i'm currently working on a older notebook with a readon mobile hd 3650 and directX11.1 under windows 8 release preview

here is a sceenshot of the problem.. that explains more than words

i've got the same issue in diablo 3 for example

on nvidia gpu's there is no problem ..

i believe this is a driver problem but of cause this can be my fault as well..

i created the device with the following flags:

BgraSupport, VideoSupport, Debug

here is my rasterizer state:

CullMode = CullMode.Back,

FillMode = FillMode.Solid,

DepthBias = 0,

DepthBiasClamp = 0,

SlopeScaledDepthBias = 0,

IsAntialiasedLineEnabled = false,

IsDepthClipEnabled = true,

IsFrontCounterClockwise = false,

IsMultisampleEnabled = false,

IsScissorEnabled = false

are there any solutions or advices to fix this problem?

i ordered a tablet with an 6920 chip.. will this show the same issue?

Re: Radeon Mobile HD driver bugs under windows 8

i think i fixed it.. .

if the device creating flag "VideoSupport" is not set, everything looks fine
