d3d10 error (World of Warcraft) #14
Comments
Yes, there is no D3D10 support at the moment and it's not something I'm going to work on any time soon. Out of curiosity, which application were you testing? |
Though so.
Unigine Valley works good at maybe 2/3 of native linux performance (not tested accurately). |
Attaching and apitrace of starting WoW. The game should be using d3d11, but they seemingly do something weird in startup. |
Interesting. I am eventually hoping to get WoW to run with DXVK for more performance than the current D3D11 atm.. I do wonder tho... When i game is DX11, it might not be "pure" DX11, and doing some calls to DX10 functions (and possibly even DX9). In WoW's case, the game engine is a old engine with new functions on top of old functions.. on top of even older functions. I am no programmer, but i kinda think that if i create a 3D program, it can utilize DX"current version and older"? Its only if i put in some new DX function that i really can say it "requires DX11" in that case, but still keep the DX9 code for other stuff.. ie. i can use DX9 calls to put up text-boxes, DX10 to create some trees, and DX11 to create the shaders... all in one program. Or am i totally wrong in my assumptions? (Cos that WOULD explain problems in general with things like WoW) Just to make sure tho, you "force" DX11 with the option I am planning on doing some tests to this myself, so keep this going :) |
I am indeed forcing with |
SSAO (Ambient Occlusion) uses DX11.. outline of models when you hover the mouse over them uses some DX11 functions.. Particles i guess.. some shading. However, i think much of the "old world" still uses DX9 functions, as the models/textures++ is "old". Still might be drawn in DX11, but i would not at all be surprised if Blizzard has cut quite a few corners with their programming. |
Lets see what the next version brings, it looks like the remove old code this time.
|
Maybe this is because of Windows? |
How much difference would DXVK make to a game like WoW? I get about 30% GPU utilization so it's CPU limited. Does DXVK have a lower CPU overhead than wine's DX11 implementation? If it's just more efficient for the GPU I don't think it will make any difference, will it? |
@TomBZombie The whole idea of DXVK is to make use of a lower level API as to reduce/eliminate the overhead in running DX11 on top of OpenGL. So it should especially prove useful in games like WoW where the framerate is already severly CPU limited :) |
@TomBZombie You can test with wine-staging, but the problem is as was posted at start of thread, that wow is not a "pure" dx11 code it seems, and will have problems. To the question: Since DX11 in windows have quite more fps than wine w/dx11 now, dx11 -> Vulkan would improve the rendering a lot and hopefully match that of windows. Still would not be "night & day" comparably when it comes to fps, as much of the fps limitation is not local hardware, but more the "talking back and forth to servers" that all MMO's do :) |
This issue appears to have been resolved by recent commits, if you have DXVK_FAKE_DX10_SUPPORT=1 set. However, there's still an issue here. On both live and beta, on launch of the game I'll either get a black screen and nothing else, or graphics will start to load (may get the title screen, may not, but the HUD renders for a couple frames) and then freeze entirely. Nothing obvious at all in the logs with debug enabled. I have found that on beta (not on live, sadly), if I set DXVK_FAKE_DX10_SUPPORT=0 and attempt to launch the game, it indicates that my graphics hardware has changed and prompts me to reset to defaults, then fails to launch as expected. If I then set it back to 1, it prompts me again, and on clicking yes the game launches and runs perfectly. If I exit and start it again, it's back to the previous behavior with the black screen/freeze. If logs might be helpful, I could upload them, but I'm only using the standard logging with the debug level and saw no errors of any kind. Also, if you'd prefer this be opened as a separate issue, I'm more than willing to do that. Don't want to hijack something that might be ready to close. |
I saw that issue, but didn't want to interfere with it because it was specifically a radv issue with graphics corruption, instead of a hang/crash behavior. I can jump over there though if you want. |
@isugimpy, you need install both x64 and x32 versions of DXVK to WoW work fine. |
Oh, I know I don't need PBA. I just already had it installed as my system version of WINE and kept using it. I realize the extra patches aren't in use once DXVK takes over. |
Given that the beta version seems to work, I'll close this one. |
err: DxgiAdapter::CheckInterfaceSupport: No D3D10 support
Is this to be expected?
