Hello, I am quite excited about my new PC although its midrange at best. My previous one was very old; and for example, could barely run something like Fortnite.

What I want to make sure is that this new PC is not defective and that these issues are 'normal'.

I first noticed the choppiness in Rocket League. Oddly, this choppiness is not necessarily tied to FPS drops and it is most frequent with a locked FPS at 60, with vsync off. You'd think locking FPS to my native monitor's refresh rate wouldn't be an issue. My best analysis would be that the choppiness is a result of a series of screen tears - screen tears that are hard to detect with the naked eye, but so quick that it produces this "choppy" feeling. To fix the sluggish feeling, all I did was unlock my FPS cap to 120 (in Rocket League) and the problem seems to be completely resolved.

Now, its a bit of a different story in Fall Guys. Without vsync, the game is still locked at 60 FPS (probably because it detects my monitor). Unfortunately, Fall Guys runs worse on this PC than my super old one... Again, enabling vsync seems to fix the issue (although I had a stutter or two, which should NEVER happen on a game like this).

Lastly, a game like Fortnite runs very well on this new PC. I understand that I have single channel ram, but that shouldn't cause this on 'easy-to-run' games. Rocket League is mostly fine, but why should I HAVE to bring my cap to 120 on a 60 hz monitor? Could this just be a monitor (60 hz) compatibility issue with my GPU/CPU? Is it normal? Should I return the PC and get another one?

Please let me know, thank you very much.

By the way - yes I'm caught up on all my drivers.

Your memory is running slow and only in single channel mode. At a minimum, you should've bought a 3200MHz kit (2x8GB) for that system. Ryzen CPUs need faster memory to perform well.
Okay, so nothing faulty right? I'm trying to find a suitable upgrade for the ram to become dual channel - Here is what it looks like inside my PC View: https://imgur.com/PcnsNLB


Next, here's a purchasable link I could find to best fit: https://www.bestbuy.com/site/adata-xpg-ax4u300038g16sz-z1-16gb-2-x-8gb-ddr4-sdram-memory-kit-sliver/6420817.p?skuId=6420817&ref=212&loc=1&ref=212&loc=1&gclid=Cj0KCQjw8fr7BRDSARIsAK0Qqr64l2CyccsD3427n-5aIpp1qnjdKJb74Vud2_gOn6s0LwKO2UIPzQsaAm3yEALw_wcB&gclsrc=aw.ds

Here is a validation link for my PC specs: https://valid.x86.fr/d72xye

In games where I cannot uncap the FPS from 60 - the screen tearing is unbearable to the point that it feels like its running at 30 fps - but the FPS stays at 60+ at all times, no frame drops are associated. It comes and goes intermittently, and gets so bad sometimes that I feel the audio will even jitter along with it (although not sure). The issue is usually either fixed with vsync on (causes horrible input lag, not preferred) or uncapping the framerate from 60.

In games like Fall Guys, it is nearly unplayable as the screen looks like its convulsing, or just very jittery visual-wise. You cannot uncap the FPS in FG if you're on a 60 hz monitor for some reason (an oversight by the devs).

I've tried 3 different 60 hz monitors in my house; Fortnite, for example, presents no issues. It runs like a charm (even in intensive areas that require a lot of memory). but I can uncap FPS in Fortnite.

Fortnite, for example, presents no issues - it runs like a charm (even in intensive areas that require a lot of memory) - but I can uncap FPS in fortnite.

So, is this a defective hardware issue? Is it just normal? I am not sure... You'd think 60 FPS wouldn't cause more issue on a 60 hz monitor than it would at 120 FPS or 200 FPS. All drivers are up to date. No overheating or anything else odd is detected.

Let me know, thank you. Btw, although I shared my cpuid link, here is the link to the prebuilt I purchased: https://www.bestbuy.com/site/cyberpowerpc-gaming-desktop-amd-ryzen-5-3600-8gb-memory-amd-radeon-rx-580-2tb-hdd-240gb-ssd-black/6362427.p?skuId=6362427
