We are using DLSS newest plugin for UE5.6 on our game, and we found that when we enable DLSS and keep camera not move for a while, some white dot artifact appearance (almost on static object’s surface), we notice some games have same issue(https://www.reddit.com/r/ArenaBreakoutInfinite/comments/1mn6boi/dot_artifacts_when_using_latest_dlss_4_presets/)
If we turn on r.NGX.DLSS.DenoiserMode = 1, the artifact disappear but the GPU time increase 33%(not acceptable), any advice for help?
Hi there @zhouchangtai94, welcome to the NVIDIA developer forums.
Can you share a screenshot maybe?
I’ll check if I can get some expert feedback.
Thanks for your reply
Sorry for certain reasons, I am unable to share the actual screenshot of the game currently in development. However, the graphical issues we are encountering are consistent with the screenshots below, we found in other player/developer’s discussion and the trigger condition is also the screen remaining static for a period of time, which leads us to suspect that DLSS itself cause this issue.
As I mentioned above, adjusting parameters( r.NGX.DLSS.DenoiserMode ) can fix this issue, but the resulting increase in GPU processing time comes at an unaffordable cost for us. Is there a better solution?
And our tests show that the UE55 plugin does not have this issue.

Furthermore, we observed a performance increase about 30% when comparing the DLSS integration in UE 5.6 against UE 5.5. Are there some insights into this variance? We need to know if this is an unavoidable trade-off. We are currently evaluating a rollback to v5.5 to mitigate both the dot artifacts and the increased computational cost.
