My RTX 4070 Super is showing very low-resolution, unstable shadows, while grass and other textures constantly pop in and out or appear to float. The problem occurs in every game I have tested, so it does not seem to be limited to one title. I have already reinstalled the graphics drivers with DDU, cleared shader caches, tried older NVIDIA drivers, toggled DLSS, and tested the GPU's VRAM, 3D, and power stability with OCCT without errors. PCIe is running at x16 Gen 4, and Resizable BAR is enabled.
System specifications:
- GPU: RTX 4070 Super
- CPU: Ryzen 7 5800X3D
- Motherboard: Gigabyte B550 Gaming X V2
- Memory: DDR4-2666 with no overclocking or XMP profile
- Storage: Kingston NVMe SSD, reporting 92% health
- PSU: 750 W, passed OCCT testing
- Operating system: Windows 11
- Driver: NVIDIA Game Ready 617.14
The SSD's extended health test also completed successfully: it reported 0 media/data integrity errors, no logged errors, 48°C, and 8% estimated wear. What else should I test? Could this still be a faulty graphics card or VRAM issue, or is there another software or hardware setting I may have missed?

Updating the motherboard firmware and testing with default BIOS settings would be worthwhile. Also verify that the GPU is fully seated and that its power connector is inserted completely. Since the problem happens in all games and survives driver cleanup, hardware isolation is more useful now than repeatedly reinstalling drivers.
This still sounds suspiciously like a graphics memory or GPU rendering problem, even though the OCCT test passed. Synthetic tests do not always reproduce every real-world rendering fault. If the issue remains after testing with a fresh Windows installation and current firmware, the graphics card may be defective and an RMA would be reasonable.
You have already ruled out most of the obvious driver and stability causes. I would reseat the graphics card and reconnect its power cable, then check whether the motherboard firmware has a newer version. A clean Windows installation on another drive is also a useful way to eliminate hidden software or configuration problems.
I’ll try installing Windows on my secondary drive so I can rule out the current installation. I’ll also check for a newer motherboard firmware version.
The storage report looks healthy: the NVMe drive passed its extended self-test, has no media or integrity errors, and is running at a normal temperature. That makes the SSD an unlikely cause. You can also test each memory module individually with a bootable memory diagnostic, preferably overnight, to rule out intermittent RAM errors.
I’m going to use a separate Windows installation as a final software check. If the artifacts continue there, I’ll pursue the card’s warranty replacement.
