Bug ID: 104744 Summary: [r600] Total War: Warhammer black textures and flickering. Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: freedesktop@lanig.email QA Contact: dri-devel@lists.freedesktop.org
A friend of mine installed Ubuntu to play the non-cross-platform game Total War: Warhammer with me. Unfortunately he had issues with black empty spaces where textures should be. But it worked for me without any issues with RadeonSI(RX 480). Then I recommended adding the Padoka PPA and to update the system.
That was a big fail. As a reward he also got heavy flickering additionally. He also mentioned weird colors where the black missing textures were before with activated graphics options. So I would like to report mainly that the current version seems to be worse than the one delivered with Ubuntu, at least for this particular game.
He can't really provide further help and I can't access the system in any way. But I hope that an r600 developer who owns such GPU could hopefully have a look in the issue.
His System: Ubuntu 17.10 Intel Core i5 2500 AMD Radeon HD 6950 2GiB 16 GiB RAM
Thanks anyway to whoever reads this - these GPUs might be old but such occurrences don't make a good impression at all to people who are trying out Linux.

--- Comment #1 from Roland Scheidegger sroland@vmware.com --- There is probably a reason why the game requirements state rx480 as a minimum... Even on macs its says amd cards newer than 2014, which excludes everything pre-gcn. I wouldn't be surprised at all if it actually fails due to the number of supported texture units, there are definitely games out there which require more than what pre-gcn hw can do. (With d3d10 apps can use 16 samplers and 128 resources, but with GL since resources and samplers aren't separated they are restricted to whatever the hw can do for samplers for resources too, which is 32 for newer hw (actually there's no hw limit but that's the limit just about every gl driver from any vendor will support), but pre-gcn chips can only do 18.) This would be mostly unfixable (well technically it would be fixable using some real ugly and complex hacks trying to deduplicate samplers but I doubt anyone will ever implement it). Albeit this is just a wild guess, it's possible there's legitimate driver bugs which cause it to misrender.
