Tearing down the main straight at Kyalami in Assetto Corsa Competizione (ACC) requires focus. But nothing breaks immersion faster than seeing a blurry mess in your rear-view mirrors. If you have noticed trails behind cars, you are likely asking: Does DLSS cause ghosting? This DLSS mirror ghosting ACC issue is a common headache for South African sim racers chasing high frame rates while maintaining visual clarity.

Understanding DLSS and the Ghosting Phenomenon in ACC

Deep Learning Super Sampling (DLSS) is a revolutionary tech that uses AI to upscale lower-resolution images. This allows you to run demanding titles at higher frame rates. When you equip your rig with high-end NVIDIA graphics cards, you expect a crisp image. However... because DLSS relies on temporal data from previous frames... fast-moving objects can sometimes leave a "ghost" or trail.

In Assetto Corsa Competizione, this is most visible in the mirrors. The game often renders mirror reflections at a different rate or lower resolution than the main viewport. This discrepancy confuses the AI algorithm, leading to the dreaded DLSS mirror ghosting ACC effect that distracts you during a tense overtake.

Why Does DLSS Cause Ghosting in Sim Racing?

Ghosting occurs when the motion vectors provided to the DLSS algorithm do not perfectly match the visual changes on screen. Since sim racing involves high-speed movement and rapid perspective shifts, the AI sometimes struggles to "clean up" the previous frame data quickly enough. While premium MSI graphics cards offer the raw power to push high refresh rates, the software implementation in ACC specifically struggles with how mirror textures are handled.

If you are struggling with mirror ghosting in ACC, try updating your DLSS .dll file manually using a tool like DLSS Swapper. Often, the version shipped with the game is outdated. Moving to version 3.5 or newer can significantly reduce trailing artifacts on moving objects in your rear-view mirrors.

Comparing Upscalers: Are There Alternatives?

If the ghosting becomes unbearable, you might look at other upscaling technologies. For instance, Intel Arc graphics cards use XeSS, which handles temporal data slightly differently. While it may not always match the sheer performance of NVIDIA's solution, some users find the ghosting profile more acceptable in specific racing titles.

Similarly, users with AMD Radeon graphics cards can utilise FSR. While FSR can also exhibit shimmering, it does not always produce the same "smearing" effect seen with certain DLSS versions in ACC. For those working on professional simulations or high-end design, even specialised workstation graphics cards can be used to test these visual discrepancies, though they are rarely the first choice for pure gaming.

How to Minimise DLSS Mirror Ghosting in ACC

To get the best out of your hardware, try these steps:

  1. Set DLSS to 'Quality' or 'Ultra Quality' to provide the AI with more data.
  2. Increase the Mirror Quality settings in the ACC options menu.
  3. Disable Motion Blur, as this can exacerbate the appearance of ghosting.
  4. Ensure your GPU drivers are updated via GeForce Experience.

Spending R15,000 or more on a GPU should result in a stellar experience. By fine-tuning these settings, you can enjoy the performance boost of AI upscaling without the distracting trails in your mirrors.
