[Bug 57022] Graphical and color distortions in The Witcher [d3dx9_35.dll]

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=57022 --- Comment #12 from Stian Low <wineryyyyy(a)gmail.com> --- Created attachment 81055 --> http://bugs.winehq.org/attachment.cgi?id=81055 Screenshot SwiftShader vs Windows rendering practically identical including shadows not to be confused with lighting bug Screenshots show consistency between SwiftShader via d3dx9_35.dll builtin and Windows with shadows appearing/disappearing based on camera angle which should not be confused with the actual bug which seems seems more related to rendering light which causes flickering and/or colors too bright like Shani's hair. Notice shadows under table appear for cam view over left shoulder (top) but disappears for view over right shoulder (bottom). Again, normal behavior that also happens for Windows. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Confirming SwiftShader d3d9.dll does in fact depend upon d3dx9_35.dll but renders without bug and therefore compatible with it as built-in. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=57022 --- Comment #10 from Stian Low <wineryyyyy(a)gmail.com> --- (In reply to Stian Low from comment #6) > Created attachment 81034 [details] > Screenshot only tongues and hair rendered when skipping > d3dx_effect_SetTechnique() for wine-11.9-f72272396b7 (In reply to Stian Low from comment #8) > However, built-in d3dx9_35.dll works with SwiftShader d3d9.dll as native > which seems to indicate built-in d3d9.dll and d3dx9_35.dll have > compatibility bugs. SwiftShader d3d9.dll actually seems to render independent of d3dx9_35.dll because d3dx_effect_SetTechnique() hack has practically no impact on SwiftShader rendering which produces practically identical results as native d3dx9_35.dll and Windows runs. Maybe d3dx9_35.dll calls are actually supposed to be skipped/ignored? I'll keep looking for rendering differences but so far they seem very subtle if they exist. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 57022] Graphical and color distortions in The Witcher [d3dx9_35.dll]

http://bugs.winehq.org/show_bug.cgi?id=57022 --- Comment #8 from Stian Low <wineryyyyy(a)gmail.com> --- Created attachment 81054 --> http://bugs.winehq.org/attachment.cgi?id=81054 Screenshot bug fixed with built-in d3dx9_35.dll and native SwiftShader d3d9.dll (Google CPU-based renderer) Confirming native d3dx9_35.dll works with built-in d3d9.dll. However, built-in d3dx9_35.dll works with SwiftShader d3d9.dll as native which seems to indicate built-in d3d9.dll and d3dx9_35.dll have compatibility bugs. Same d3dx logs are produced for SwiftShader d3d9.dll which seem to be red-herrings: 0158:fixme:d3dx:d3dx_effect_ValidateTechnique flags 0x1, load_path 00000000, dll_characteristics 00000000, name 01C6EEF4, base 01C6EEF0. LIBGL_ALWAYS_SOFTWARE=1 for X11 without EGL also runs CPU based rendering like SwiftShader but reproduces the bug. Therefore, if bug is not caused by multithreading difference between SwiftShader and built-in d3d9.dll CPU-based rendering, then built-in d3d9.dll may indeed also have bugs. Be aware, GOG Witcher installer replaces some built-in dlls for c:/windows/systeme32 and c:/windows/syswow64 including d3dx9_35.dll which caused some confusion for me. Therefore I backed up original system32 and syswow64 before installing witcher to replace witcher modded directories and guarantee built-ins were used while testing. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59317] Need for Speed Most Wanted (2005): Up is triggered continuously without pressing a button on gamepad

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=59317 StewVed <stewved(a)gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |stewved(a)gmail.com --- Comment #7 from StewVed <stewved(a)gmail.com> --- (In reply to SeongChan Lee from comment #5) > The change was introduced in this MR by me: > https://gitlab.winehq.org/wine/wine/-/merge_requests/9789 Your patch seems to make the Y axis of XBOX game controllers not work for DInput, though XInput and Windows.Gaming.Input appear to work fine (joy.cpl) Since there are many DInput-based games (Star Wars Episode 1 Racer, Telltale Batman, NFS Most Wanted, The Grinch reported so far), and the problem can easily be seen in wine control joy.cpl > DInput tab, can your original commits please be reverted until a better solution is figured out? There is a patch that forces 32-bit back onto the hid: https://github.com/elgabo86/gwine/blob/main/patches/gamepad_axis_32bit_fix.… https://bugs.winehq.org/attachment.cgi?id=80571&action=diff on the better solution front, I see your good idea of determining the size: static BYTE hid_device_determine_axis_size(LONG min, LONG max) { if ((min >= 0 && max <= 255) || (min >= -128 && max <= 127)) return 8; if ((min >= 0 && max <= 65535) || (min >= -32768 && max <= 32767)) return 16; return 32; } and that should be fine, though I think it will NEVER return 32 because the max (-32768 to 32767) is in hid_device_add_gamepad and is INT16 and USHORT, but some other part of the code seems to need the size to be 32 for the XBOX Gamepad Y axis to work?!? Just to say, everything else on the entire gampad appears to work perfectly, so I'd love to know what is special about the Y and rY axis. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
