Lag Spikes on Graphics-Intensive applications

Hello there,
I’m running KDE Plasma on Manjaro (stable) on my Surface Laptop 3. Out of the box drivers, (I would think it should be fine considering the hardware is Intel).

Here is the INXI command, if it helps.

When I try to run graphics-heavy applications, such as steam games (and even discord calls at times), I experience massive lag spikes for a minute or two at a time. During this time, music stutters and the entire desktop hangs and becomes unresponsive, as well as abysmal FPS on games (5-10).

At first I thought it was a memory issue, but I have 16GB of memory which is being around 50% utilized during the lag spikes, as well a a swap partition which too is being utilized, but barely. During the lag, CPU usage shoots up to 99.5%, but apart from that the other ‘vitals’ seem fine.

I have reinstalled Manjaro and used different desktop environments too, but to no avail. I’m sure my hardware is capable of running such applications, and it doesn’t seem to be a heavy load based issue (considering discord calls break too), so I think it may be something to do with drivers.

Does anyone have an idea of what’s up? I’ve looked at other forum posts, but everyone points to memory issues (which I doubt are the problem here). I’m new to the forum so I don’t know if I’ve provided enough info, but any and all help is appreciated.

Hi and welcome to the forums, please post output of:

Here it is.

Well at least it seems you have the proper drivers installed i guess :wink:
As i use a different GFX card, im unable to help you further, hope others using an Intel Iris Plus Graphics G7 can help further. :woman_shrugging:

Alright, no problem, thanks for trying! I’ll definitely check in on the wiki.
