Yea you are right these statements are somewhat contradictive.

To be honest, i havent noticed a lot of stutters playing without gsynyc or vsync since im having a very bad expierience when playing without gsync or gsync. The games feel very unsmooth and also there is tearing of course. even with a capped framerate i dont get a smooth and consistent frametime when playing without gsync/freesync so i could exactly tell if there are less spikes since the frametime graph is very inconsistent without gsnyc/vsync

sorry for the misconception.

Next time i get a spike, ill hover over the spike in msi afterburner and check the ms.

Here i checked the frametime as the spice accured.
Fps went down from 141 to 125 and Frametime from 7,0ms to 63,3.

Is that information any helpful?

You had a 63ms frametime spike.

This just means, for a period of about 9 frames in a single second (e.g. 9 out of 141 frames), the previous frame repeated, as the system processed the next frame that had a render time higher than a single refresh cycle (63ms render time of a single frame vs. the usual 7.1ms render time of a single frame @141 FPS).

That duration of a frametime spike obviously isn't ideal, but it's within range of disk access and/or asset loading. Whether it is being caused by that in your case is another question, and would require further investigation, but the likelihood of it being caused by G-SYNC is almost zero, and would likely occur with G-SYNC off + V-SYNC off as well.

As for the reason you notice these spikes less with G-SYNC off + V-SYNC off when compared to G-SYNC on + V-SYNC on, the answer is simple; contrast. These spikes get lost in the tearing with the former, but are more obvious with the latter, as it's otherwise perfectly smooth until the spike(s) occur.

Okay that seems understandable.

What investigation could I do from this point? Sure there isnt anything I could do to eliminate these stutters?
Maybe even upgrade hardware or invest in a 240hz Monitor ?

If these are being caused by the game engine itself, there's pretty much nothing you can do. In the case of Valorant (or any online game), some spikes at this severity could simply be caused by random network access, also something you can't do much about.

If they aren't (something you would have to determine first; good luck), to start, you'd have use tools like LatencyMon to monitor your system processes while playing the game to see if there are any problem drivers or process causing or exacerbating these spikes. Irony is, running LatencyMon in the background can actually sometimes cause more spikes, and thus false positives (same goes for RTSS/Afterburner polling time FYI; keep it at or near default, or it can cause more frametime spikes as well).

Reduce them in some instances for some games? Maybe. Eliminate them in all instances? No.

Better hardware will only reduce (not eliminate) these instances if it's the very thing causing them in the first place. If it's the given game causing them, then, no.

As for a higher refresh rate display, that would not fix this; the spikes originate on the system-side, not the display-side. For instance, a 63ms frametime spike at 237 FPS (240Hz) would simply occur over a 15 frame period (4.2ms x 15 = 63) instead of a 9 frame period (7.1ms x 9 = 63.9), and would look the same as it does on a 144Hz monitor.

I will test to play without gsync and vsync altogether now. How would the best settings for that look like? Just turn both off, disable fps cap in rtss and set low latency to ultra?

Effectively, yes.
