Issues with Artifacts/Graphics following the introduction of a new card.
Hello Community,
In November 2024 I purchased a new graphics card – a Zotac 4070 Super and a Gigabyte 2070Super. After that, I noticed some games displayed artifacts and graphical glitches, mostly consisting of green and pink dots appearing and moving around. These issues didn’t occur consistently or in every game. The operating system itself seemed unaffected; the dots were limited to certain titles. Initially, I considered updating the drivers, but after reinstalling the entire drive (including using DDU), the problem persisted. Still, it doesn’t happen very often now.
Next, I checked Windows and performed a full reinstall. The same issue continued. I repeatedly monitored temperatures using HwInfo. Over the past few months, the average temperature was around 75°C, with a hotspot near 80°C.
I experimented with different cables, other displays, and various GPU slots, but nothing resolved the problem. I updated my chipset and BIOS, tried repairing affected games, and ran benchmarks using OCCT. All components – CPU, RAM, GPU, VRAM – showed normal performance after about 10 minutes of testing.
Interestingly, the artifacts only appeared in specific games such as Last of Us (shaders like water), Anno 1800 (water effects), and Tarkov (small dots everywhere). In contrast, games like Assassins Creed Shadows were completely unaffected.
Here’s a video showing the artifacts:

Curious observation: when the game goes dark, the UI and other elements remain intact, except for the dots and artifacts behind the inventory screen. It’s quite strange.
Anyone have any insights or suggestions?
Thanks ahead of time,

Your PSU isn't providing enough power for the recommended wattage:

If you're running overclocking tasks (CPU, GPU, memory), pause and return to the default settings. This will reduce the strain on the GPU.
It's also conceivable your GPU is faulty; testing it on another system may clarify this issue.
The simplest step to try is confirming your motherboard BIOS is completely current.
Consider trying on a different machine with the correct wattage (or higher) power supply, or replace it with a suitable one.
I understand. I might consider using the PSU (750W Seasonic) from my brother. Thanks!
Try removing the shader cache
"To either use the NVIDIA Control Panel to disable and then re-enable the shader cache, or manually remove the cache files in the Windows Explorer.
Method 1: Using the NVIDIA Control Panel
Launch the NVIDIA Control Panel: Right-click your desktop and choose "NVIDIA Control Panel".
Go to Manage 3D Settings: Click on "Manage 3D settings".
Turn Off Shader Cache: In the Global Settings tab, locate "Shader Cache" and set it to "Disabled".
Apply Changes and Restart: Click "Apply" then restart your computer.
Restore Shader Cache: Once restarted, return to the NVIDIA Control Panel and set "Shader Cache" back to "Driver Default" or your preferred option."
Method 2: Deleting Cache Files Manually
Open File Explorer: Launch Windows File Explorer.
Visit the Shader Cache Folders:
GLCache: %USERPROFILE%\AppData\Local\Temp\NVIDIA\GLCache.
DXCache: %USERPROFILE%\AppData\Local\Temp\NVIDIA\DXCache.
NV_Cache: %USERPROFILE%\AppData\Local\NVIDIA Corporation\NV_Cache.
Remove Contents: Select all files and folders inside each folder and delete them.
Restart your PC: After removing the files, restart your computer."
Ensure all power cables are compatible with their respective PSUs and avoid mixing them.
Good advice, will test it out first before switching PSU.
Absolutely!
