Question about game glitches?
Question about game glitches?
Hello, this is my first time joining the forum and I need some guidance regarding a build I recently sold to a friend. Yesterday I completed the build and handed it over, but shortly after he started experiencing severe stuttering in both Cod Warzone and Helldivers 2. I was observing while he played Warzone at a stable 120fps, and around three minutes later the frame rate dropped drastically to just 9fps or less—lasting for 2 to 3 seconds instead of the usual 0.1 or 0.5 seconds. This issue occurred only in those two games.
The build was assembled from parts I had leftover from my own PC and additional components I purchased to finish it. I’m certain the used parts are functional, and it’s been less than two months since I stopped using them due to an upgrade. The stuttering is limited to specific games.
I’ve tried several solutions so far:
- 3DMark Steel nomad test: around 4,900 score without stutter
- Fresh Windows 11 installation
- Reducing the GPU power limit to 80% in MSI Afterburner
- Cleaning and reinstalling Nvidia drivers using DDU
- Disabling and enabling the Resize bar
- Activating or disabling XMP profiles
- Changing PCIe x16 settings from auto to 3.0
I also tested both the PSU models listed and my own 1000W Asus Rog Strix. I’m planning to rest after this, hoping for some sleep once I’m back from work.
PC specifications:
- CPU: Intel Core i9-11900k (new)
- Motherboard: Biostar Z490GTA EVO (open box, no prior use)
- RAM: 16GB x2 Kingston fury DDR4 3,200MHz (used PC)
- SSD: Kingston NV2 1TB M.2 x2 (brand new)
- GPU: Zotac RTX 3080 Ti (used PC)
- Power Supply: NZXT C850 80+ Gold (new)
- CPU cooler: Deepcool AK500
Temperatures for both CPU and GPU range from 40 to 75 between HD2 and Warzone, which doesn’t seem to be overheating.
I look forward to your advice.
Check the details in Task Manager and Resource Monitor to see how the system performs.
Examine both tools at once but keep only one open during use.
Observe which resources are being consumed and how they affect performance.
The goal is to identify any shifts or issues that cause stutters.
Possible causes may be configuration errors or overlooked settings.
Further troubleshooting will be needed.
The failure appears to be related to a heat problem. Check the HWmonitor for individual core temperatures; if any read 100°C in red, that core slowed down and ran at a reduced clock speed until it stabilized. Identify the case model and fan setup. Also, confirm whether the motherboard BIOS is up to date.
Is he just playing online games? Return the computer to your home and attempt to play again. If the stuttering ceases, the issue likely lies with his internet connection. If moving the PC is difficult, run a terminal command and execute ping 8.8.8.8. Keep it running during playback and observe latency after any stutter. If latency becomes excessively high—such as hundreds of milliseconds—it probably indicates a network problem. Additionally, using streaming apps like Discord can also lead to stuttering.
PSU has never been used before; purchased it recently. During gaming, CPU usage hovers near 60%, while GPU spikes from 80% to 99%. RAM utilization remains around 50% (Helldivers 2 and Cod Warzone, currently).
Case is an antec, I don’t recall the model details. It has four stock fans and its own fan on the cooler. I ran it yesterday with the panel open and the AC set to 20°C blowing near it.
I used HWmonitor but can’t remember seeing individual cores. I’ll check that. Apart from that, HWmonitor showed a general CPU temperature between 78-79°C.
I updated the Motherboard BIOS about two months ago so it would recognize the 11th generation CPU until then. Then I used a 10th generation and received the latest update at that time.
It can’t be, he’s my roommate and we share the same connection.
I hope it could be so easy

(We attempted both ethernet and Wi-fi using two different antennas)
Which GPU are you currently utilizing?
Place that GPU on your roommate's machine, adjust settings accordingly, and run a test.
Outcome?
Fair enough: it's always a bit awkward when things go wrong while trying to assist friends and family.

Extra troubleshooting might be useful or give insight.
It's normal for a moved part (in any comparable case) to fail in some way....
The goal is to troubleshoot effectively by using methods that help focus on the possible causes.
