Pixel Problems: Investigating Aliasing Issues on the RTX 3080


“Could an expert advise whether the severe aliasing issues I’m experiencing in my games are due to a defective RTX 3080 graphics card, or are they a consequence of gaming at a 1080p resolution? My system is equipped with an i7 9700k CPU, 32GB of RAM at 3600MHz, and an RTX 3080 GPU. Despite trying various settings in the Nvidia control panel, the problem persists. The image quality is noticeably poorer compared to my other PC that runs a RTX 2060, albeit at a lower frame rate. I’m considering testing with a GTX 1660 to determine if it’s indeed the GPU at fault. Additionally, while Dynamic Super Resolution (DSR) set to 4k does alleviate the issue somewhat, not all games support this feature. Any guidance on this matter would be greatly appreciated.”


When it comes to high-end gaming, the visual experience is just as important as the gameplay itself. A gamer has brought to attention a concerning issue of severe aliasing with their RTX 3080 graphics card, despite having a robust system configuration that includes an i7 9700k CPU and 32GB of RAM. The aliasing is so pronounced that it’s comparable to viewing individual pixels, and the image quality is inferior to that of a system with an RTX 2060 GPU.

Aliasing typically occurs when the resolution of the display does not match the resolution at which the game is rendered. In this case, the user is gaming at 1080p, which is below the RTX 3080’s capabilities, potentially leading to underutilization of the GPU’s power. This mismatch can result in jagged edges and pixelated images, especially noticeable in high-motion scenes.

Troubleshooting Steps


Driver Updates

: Ensure that the latest drivers are installed. A fresh driver installation can sometimes resolve unexpected graphical issues.


Nvidia Control Panel Settings

: Tweaking the anti-aliasing settings within the Nvidia control panel could provide a solution. However, the user has mentioned that this step did not rectify the issue.


Monitor Swap Test

: Using the same monitor to compare the output from both the RTX 3080 and the RTX 2060 can help isolate the problem to the GPU if the issue persists.


Testing with Another GPU

: Substituting the RTX 3080 with a GTX 1660 will further clarify if the GPU is at fault.

Dynamic Super Resolution (DSR)

DSR is a feature that renders a game at a higher resolution and then downscales it to the native resolution of the monitor, providing a crisper image. While this has helped the user to some extent, it’s not a universal fix as not all games support DSR.

Expert Opinion

Without physical inspection or diagnostic tests, it’s challenging to definitively conclude whether the RTX 3080 is faulty. However, if the aliasing issue is not present with other GPUs like the RTX 2060 or GTX 1660 on the same system and monitor, it could indicate a problem with the RTX 3080.


The user’s proactive approach in troubleshooting is commendable. If the issue is isolated to the RTX 3080 and persists across various games and settings, it may be advisable to contact the manufacturer for a warranty claim or further technical support. In the meantime, utilizing DSR where possible and experimenting with different in-game graphical settings may provide temporary relief from the aliasing issues.
