My RTX 4070 Super is rendering very low-resolution, unstable shadows, while grass and other textures pop in and out, appear detached, or seem to float. The problem occurs in every game I have tested, so it does not appear to be limited to one title.
My system includes an RTX 4070 Super, Ryzen 7 5800X3D, Gigabyte B550 Gaming X V2 motherboard, DDR4-2666 memory running without overclocking, a Kingston NVMe drive, and a 750W power supply. I am running Windows 11 with NVIDIA Game Ready driver 617.14.
So far I have used DDU for clean driver removal, cleared shader caches, tried older NVIDIA drivers, tested with DLSS enabled and disabled, and run OCCT VRAM, 3D, and power tests without errors. The graphics card is connected at PCIe 4.0 x16, and Resizable BAR is enabled. The SSD reports good health, and the system passed its storage self-test and memory testing.
I am considering installing Windows on another drive to rule out software corruption, but I would appreciate any other suggestions. Could this still be a graphics-card or VRAM fault even though stress tests pass?

At this stage, I would reseat the graphics card and its power connector, then check whether the motherboard BIOS has a newer version. A clean Windows installation on a separate drive is also a useful way to eliminate the operating system and software stack as variables. The memory running at DDR4-2666 is unlikely to cause these specific visual artifacts, especially if that is its rated maximum speed.
The symptoms look suspiciously like a VRAM or graphics-card problem, even though OCCT did not report an error. Stress tests can miss intermittent faults that show up during particular rendering workloads. If the issue remains after testing a fresh Windows installation, trying another known-good GPU would be a strong diagnostic step. If the artifacts follow this card, an RMA or replacement is probably warranted.
I plan to install Windows on my secondary drive first so I can rule out the current installation. If the problem continues, I will pursue the warranty route.
The storage diagnostics look normal: the NVMe drive passed its extended self-test, has no media or data-integrity errors, and is only reporting 8% usage. Its temperature is also fine, so the SSD is unlikely to be responsible for the rendering glitches. Updating the BIOS and completing a clean operating-system test are reasonable next steps, but the GPU remains the main suspect if the behavior happens in every game.

I checked the memory settings and DDR4-2666 is its maximum supported speed, so there is no XMP profile available. I will still check for a newer BIOS and try the card and power connection again.
