Very big difference in graphic performance

[Texlee]

Hello, how is it possible that super tux kart works much better in internal display that in external one?
In the internal monitor it works at 110 fps instead in the external at 60, almost twice as much.
The resolution is the same for each ones and the internal one even works at 144 Hz instead of 60 of the other one
I've an nvidia graphic card with nvidia driver installed.

Thanks

Hi. Some computers have dual/hybrid graphics. Can you give us the outputs of one or both of these commands? (you might need to install the packages)

Code: Select all

lshw -C display

(you might be asked to run that one as root)

Code: Select all

With your external monitor connected what does the command

Code: Select all

xrandr

return?

Are you mirroring your screen or running just external when you do this?

[bbbhltz]

I don't know if this is a definitive source, but...

This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device.

[Borg]

Is the external display connected via USB 3.x?

Are you mirroring your screen or running just external when you do this?

I use only the external monitor while the internal one is turned off

[Texlee]

Is the external display connected via USB 3.x?

No, via HDMI

[bbbhltz]

The resolution is the same for each ones and the internal one even works at 144 Hz instead of 60 of the other one

Your most recent post (link) says...

You external monitor is your primary running at 3840x2160 60.00Hz and your laptop screen is running at 1920x1080 144.00Hz.

While I am no expert, I think those are the maximum values you can get out of the hardware and connected devices/monitors. I think that the Nvidia card does not drive the HDMI out. Think is the operative word.

The FPS issue might be resolved by lowering the external monitor's resolution?

[Texlee]

I think that the Nvidia card does not drive the HDMI out. Think is the operative word.

Unfortunately the HDMI port is directly connected with Nvidia card only. I wish I could use the integrated and low energy graphic card, but it is impossibile.

The FPS issue might be resolved by lowering the external monitor's resolution?

I set the external monitor resolution in fullHD but the FPS are always 60. The FPS are blocked at 60 in the menu of the game too and also it is always 60 even if I set the graphic level to minimum. In addition I think that my hardware is able to obtain 110 FPS also in 4K with super tux kart.

Is it possible there is a kind of software block?

[bbbhltz]

Sorry @Texlee, don't know about software block.

The only other suggestions I have are to change the title of the first post of the thread and add more description, use the mailing list to ask for help, or the IRC room.

However, whatever application I use, I max out at 60fps, even glxgears.
So what could set this limit that I don't have with the internal monitor?

[mrmazda]

According to xrandr output provided here, the external port supports no more than 60Hz. 3840x2160 is 4X as many pixels to manage as the 1920x1080 internal @120. @144 is still much less work to do. You haven't specified the CPU that provides your IGP, so I checked a Raptor Lake i9-14900K and see it only supports 120Hz on an internal display, while externals are limited to 60Hz. Perhaps this limitation applies even though you have the NVidia 4050 onboard?

I've done several tests and the computer is behaving strangely. The most likely thing is that since the monitor is at 60Hz it cannot display more than 60 fps even if with windows I double them. At this point I really believe that there are no solutions and that the problem is linux + nvidia.

[Texlee]

But there are other strange things always on a graphic level. For example, every now and then my screen freezes for no reason. Every now and then I have the wheel that loads instead of the mouse for no apparent reason. From terminal as root I can't launch programs that use the gui. In short, many things that are not acceptable for a main and stable computer.

I was going to say too, perhaps your monitor can' t do any better. If have manual for your monitor, or search the spcecs, if you are still interested,

Better open a new thread for your freeze problems.

I tried it on windows and the fps is 110. Maybe I can't see them because the monitor is at 60Hz but the video card can generate 110.

[Linuxgaming1824]

There are actually a ton of factors involved that add up to produce the end result with graphical issues.

If you're using an external 4k display and testing games on it, you will want to consider the monitors settings,
the quality of your connection cable(hdmi will support up to 120hz display port will support above 120hz generally)
and there are different versions of hdmi and display port cables that have improved capabilities. If your monitor settings are
set for hd or tv mode instead of pc mode then it will be locked at 60 fps. Then you will also want to consider the display settings,
in the operating system as well, and if you have nvidia then you have access to the nvidia-settings app to manage your display settings, and you can configure multiple monitors from there and other related settings as well...

Also if you are using the external display and internal display at the same time, you can expect to have degraded performance,
so for the best performance ideally you will want to use display settings (such as through nvidia-settings) to disable the "internal" laptop monitor, and only enable the external display.

There are lots of other considerations too...what is your display server? Hopefully for gaming it's x11. What's your graphics card? graphics driver? what desktop environment are you using? compositor? what are the compositors settings?

Also, what options do you have in your bios/uefi system settings to alter the graphic card you are using? If you have a built-in graphics card, and nvidia too, can you disable the internal graphics card, and just use nvidia?

All of these factors, and more, add up to produce the end result: the performance you can possibly achieve with various games..
