Why Your RTX 3080 Looks Worse Than Your RTX 2060 at 1080p and How to Solve It


How can I fix the aliasing issue on my RTX 3080?

I have a PC with an i7 9700k, 32 GB of RAM at 3600, and an RTX 3080. I play games at 1080p resolution, but I notice severe aliasing in most of them. The edges of objects look jagged and pixelated, and the overall image quality is poor. I have another PC with an RTX 2060 that displays the same games much better, albeit with lower frame rates. I have tried changing various settings in the Nvidia control panel, but nothing seems to work. I suspect that my RTX 3080 might be defective, or that it is not compatible with 1080p gaming. I plan to test it with a GTX 1660 to see if the problem persists. I also tried using DSR to upscale the resolution to 4k, which improved the aliasing, but not all games support this feature. I posted this question on Nvidia’s forum, but they deleted it. I need some expert advice on how to solve this issue. I will provide some screenshots of the games as soon as possible.

Things I have done so far:

  • – Fresh driver install
  • – Installed latest drivers
  • – Enabled AA
  • – Swapped monitors
  • Answer:

    If you are a PC gamer who has recently upgraded to an RTX 3080, you might be expecting a smooth and crisp gaming experience at 1080p resolution. However, some users have reported a severe aliasing issue with their RTX 3080, which makes the edges of objects look jagged and pixelated, and the overall image quality look poor. This issue can be frustrating and disappointing, especially considering the high price and performance of the RTX 3080. In this article, we will try to explain the possible causes and solutions for this problem, and provide some tips on how to optimize your gaming settings.

    What is aliasing and why does it happen?

    Aliasing is a visual artifact that occurs when the resolution of the display is lower than the resolution of the rendered image. This means that the pixels on the screen cannot accurately represent the details of the image, and thus create jagged and stair-like edges along the curves and diagonals. Aliasing can also cause shimmering and flickering effects, especially when the camera or the objects are moving.

    Aliasing can happen for various reasons, such as the game engine, the graphics card, the monitor, or the settings. Some games are more prone to aliasing than others, depending on how they handle the rendering and anti-aliasing techniques. Anti-aliasing (AA) is a process that smooths out the edges of the image by blending the colors of the pixels, or by rendering the image at a higher resolution and then scaling it down. There are different types of AA, such as MSAA, FXAA, SMAA, TAA, etc., each with their own advantages and disadvantages.

    Why does the RTX 3080 have an aliasing issue at 1080p?

    The RTX 3080 is one of the most powerful graphics cards on the market, capable of delivering high frame rates and stunning graphics at 4k resolution. However, some users have noticed that the RTX 3080 performs poorly at 1080p resolution, and produces more aliasing than other cards, such as the RTX 2060 or the GTX 1660. This seems counter-intuitive, as one would expect the RTX 3080 to handle 1080p with ease.

    There are several possible explanations for this phenomenon, but none of them are conclusive or confirmed by Nvidia. One theory is that the RTX 3080 is overkill for 1080p gaming, and that it renders the image at such a high quality and speed that it exposes the limitations of the display and the game engine. Another theory is that the RTX 3080 has some compatibility issues with 1080p monitors, and that it does not sync well with the refresh rate or the pixel density. A third theory is that the RTX 3080 has some driver or firmware bugs that affect its performance at 1080p resolution, and that Nvidia needs to fix them with future updates.

    How can you fix the aliasing issue on your RTX 3080?

    If you are experiencing the aliasing issue on your RTX 3080, there are some steps you can take to try to fix it or reduce it. Here are some suggestions:

    • Update your drivers: Make sure you have the latest drivers for your RTX 3080, as they might contain some fixes or improvements for the aliasing issue. You can download the drivers from Nvidia’s website, or use the GeForce Experience app to automatically update them.
    • Enable AA: Check the settings of your games and enable the AA option that suits your preference and performance. You can also adjust the AA settings in the Nvidia control panel, under the 3D settings section. Experiment with different types of AA, such as MSAA, FXAA, SMAA, TAA, etc., and see which one works best for you. Some games also have a dynamic resolution option, which adjusts the resolution according to the frame rate. This can help with the aliasing issue, but it might also cause some blurriness or inconsistency.
    • Use DSR: DSR stands for Dynamic Super Resolution, and it is a feature that allows you to render the game at a higher resolution than your monitor, and then scale it down to fit your screen. This can effectively eliminate the aliasing issue, as the image is rendered with more detail and smoothness. However, DSR can also reduce your frame rate and performance, as it requires more processing power from your graphics card. You can enable DSR in the Nvidia control panel, under the 3D settings section. You can also choose the DSR factor, which determines how much higher the resolution is than your monitor. For example, a DSR factor of 2x means that the game is rendered at twice the resolution of your monitor. You can also adjust the DSR smoothness, which determines how much the image is filtered and blended. You can use DSR with any game that supports it, but not all games do.
    • Change your monitor: If none of the above solutions work for you, or if you are not satisfied with the results, you might want to consider changing your monitor. A higher resolution monitor, such as a 1440p or a 4k monitor, can greatly improve the image quality and reduce the aliasing issue, as the pixels are smaller and denser. A higher refresh rate monitor, such as a 144 Hz or a 240 Hz monitor, can also enhance the smoothness and responsiveness of the game, as the screen can display more frames per second. However, a higher resolution or refresh rate monitor can also be more expensive and demanding, as you will need a more powerful graphics card and CPU to run the games at optimal settings.
    • Conclusion


    RTX 3080 is a beast of a graphics card, but it also has some issues with aliasing at 1080p resolution. This can be annoying and disappointing for some users, who expect a flawless gaming experience from such a high-end card. There are some possible causes and solutions for this problem, but none of them are definitive or guaranteed. The best way to fix the aliasing issue on your RTX 3080 is to experiment with different settings, techniques, and hardware, and find the one that works best for you and your games. We hope this article was helpful and informative, and that you can enjoy your RTX 3080 to the fullest. Happy gaming!
