[Bug 46193] New: Incorrect display refresh rates in games & w/ dxgi-factory.exe test utility
https://bugs.winehq.org/show_bug.cgi?id=46193 Bug ID: 46193 Summary: Incorrect display refresh rates in games & w/ dxgi-factory.exe test utility Product: Wine Version: 3.21 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: vash63(a)gmail.com Distribution: --- Created attachment 62854 --> https://bugs.winehq.org/attachment.cgi?id=62854 Output of test utility with WINEDEBUG=xrandr Tested most recently with Battlefield 5, the in-game resolution selector shows odd refresh rates that are much too low - between 50-66Hz on a 144Hz display. I've attached the output from a test utility included with DXVK that also duplicates the issue with cleaner log output than the game. List of 1440p examples: 2560x1440 @ 50 2560x1440 @ 51 2560x1440 @ 52 2560x1440 @ 53 2560x1440 @ 54 xrandr correctly reports my display as 144Hz: DP-4 connected primary 2560x1440+0+0 (normal left inverted right x axis y axis) 598mm x 336mm 2560x1440 59.95 + 144.00* 120.00 99.95 84.98 Test utility from: https://github.com/doitsujin/dxvk/tree/master/tests/dxgi Also interesting is that it's detecting my GPU incorrectly as a GTX 470, not an RTX 2080, which the utility looks to be pulling from 'desc.DeviceId'. This was tested on a clean wine 3.21 install without dxvk or any other alterations. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=46193 --- Comment #1 from Henri Verbeet <hverbeet(a)gmail.com> --- I think that's mostly just NVIDIA RandR returning bogus refresh rates. At some point you could fix that by disabling the "DynamicTwinView" option, but it's been several years now since I last used the proprietary NVIDIA driver. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Running just 'xrandr' does correctly report 144Hz though, is there something else I should run to confirm that it's an Nvidia bug? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

Maybe "xrandr --q1" -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

Ok, that does confirm that this is an Nvidia issue I think. $ xrandr --q1 SZ: Pixels Physical Refresh *0 2560 x 1440 ( 602mm x 341mm ) *50 51 52 53 54 This still seems to impact wine more than other applications though - native games see it correctly as does both Gnome and KDE. Is there some better way to poll available resolutions and refresh rates that they are using? -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=46193 --- Comment #5 from George Gibbs <vash63(a)gmail.com> --- I got a reply from aplattner @ nvidia regarding this which may be helpful. I'm just going to paste it here:
The RandR 1.1 interface predates having multiple monitor support in the X server, so the only way it has to identify display configurations is with a (resolution, refresh rate) pair. The NVIDIA driver supports configurations that would look identical to RandR 1.1, so the driver assigns sequentially increasing "refresh rate" numbers so that the RandR 1.1 modes are unique. This behavior is documented in the readme: https://download.nvidia.com/XFree86/Linux-x86_64/415.13/README/faq.html#WhyI...
Nowadays, Wine could use RandR 1.2, which is aware of multiple monitors and capable of configuring the display timings (including refresh rate) and scaling parameters on a per-monitor basis. However, due to a disagreement over the intended behavior of RandR 1.2 interfaces, Wine does not use it and instead relies on the older RandR 1.1 interface. You can read more about the history of that decision here: https://bugs.winehq.org/show_bug.cgi?id=34348
