New Install of Arch with a 3070ti and graphics are laggy?

Hello all.  I recently built a new system and am running a 3070ti which in my mind performance wise should have no issues for what the card I know is capable of.  I installed nvidia and nvidia-utils via pacman.  Am running KDE plasma with SDDM.  I have 3 monitors going which work fine and resolution is correct. With nvidia-settings i can control my fans and in that regard is working like it should.  However the graphics are laggy and not smooth.  Does anyone have any suggestions??  For a 1k card I don't expect arch to be limiting its performance to the level that it is.  I don't get it..  Thank you for any suggestions.

Do you have different refresh rates between the monitors? Xorg can only sync to a single one, so it can look and feel weird on the others. One thing you can do that should in general help is enabling triple buffering on the driver with e.g. /etc/X11/xorg.conf.d/20-enabletripleBuffer.conf

Section "OutputClass"
      Identifier "nvidia"
      MatchDriver "nvidia-drm"
      Driver "nvidia"
      Option "TripleBuffer" "on"
EndSection

and restart xorg/reboot.

Other than that, with the recent developments you might be interested in trying out the Wayland session, you'll need to enable KMS for that. https://wiki.archlinux.org/title/NVIDIA … de_setting

I also have a 3070ti with multiple monitors and in my experience, it seems that NVIDIA never feels snappy with KDE no matter what fixes I apply to it. All my monitors have the exact same refresh rate, too. Opening a program makes the cursor lag and skip around when I move it, and dragging windows in general feels sluggish. My older computer has an RX 580 and KDE runs great there despite the older hardware, even with multiple monitors.

You can always try other Desktop Environments. I found GNOME and XFCE to run very smoothly with my 3070ti. I prefer the latter, but I disable the compositor and use picom instead. XFCE's native compositor makes games horribly laggy for me.
