The introduction of frame generation (FG) has been a game-changer for many RTX40-series owners. However, the AI-tech behind FG is not infallible. FG-related artifacts are an inherent problem with the frame generation AI technology (DLSS3) but can be avoided. The AI-tech behind FG basically inserts an AI-generated image in between two native images: The problem is that the AI tech sometimes fails to render the AI-image properly (causing artifacts). Factors that increase the chance of seeing these artifacts: native FPS is too low - I find that at least 30 non-FG FPS is needed for FG to work properly very fast panning very fast-moving objects very fast-moving numbers e.g. on speed-tapes I rarely see these artifacts. In fact the last time I can remember seeing them was on the dev mode FPS overlay where the numbers were changing extremely quickly: For some in-depth information about how FG works, and how it sometimes can create artifacts, I highly recommend this detailed analysis (they also talk about MSFS): https://youtu.be/92ZqYaPXxas?si=nk5bLaJPzUvg6gH4 Some examples of fast-moving objects where the AI tech fails to render accurate AI-frames (perhaps more relevant to more fast-paced games): Clearly, some people are much more sensitive to these artifacts than others. I've made many videos lately, and honestly haven't seen much of these artifacts, if at all. When considering getting a RTX40-series card, I highly recommend pairing it with a decent CPU. I have a 12900KF which IMO is working fine. Another thing: A 4090 is not needed unless you want the absolute best (and can afford it). Perhaps the biggest advantage with a 4090 is 24GB of VRAM. I've seen total VRAM usage up to 23GB. But that's an extreme example, usually it's much lower than that. In one of the most demanding locations in the sim, VRAM was about 15-16GB: I've been flight simming for more than 25 years. I've custom-built PC's for just as long. Performance has always been a problem. The most game-changing upgrade I've ever done was getting the 4090. Comments? Is it worth getting a RTX40-series card? Are people distracted by the artifacts? Hopefully this thread will generate some discussion as FG seems to be a very hot topic.- 50 replies
