NVIDIA DLSS 3 Is Poorly Implemented in Forza Horizon 5, Causing Worse Fluidity and Artifacts
Yesterday's Forza Horizon 5 update added NVIDIA DLSS 3 (and Reflex) support to the PC version. While the open world racing game was released quite a while ago, on November 9th, 2021 to be exact, the extraordinary popularity of Playground's latest game ensured its continued support.
As a quick reminder, Forza Horizon 5 became the largest Xbox Game Studios debut in terms of day-one figures with 4.5 million players and later more than doubled that feat with ten million players in the first week, another record for Xbox and Game Pass. The NPD then ratified a launch month sales record for the whole Forza franchise. On top of all that, Forza Horizon 5 also got excellent scores from critics (9.5/10 here on Wccftech) and multiple awards, including three at The Game Awards 2021, tied with It Takes Two for most wins at that event.
All that is to say, Playground Games had a lot of reasons to keep improving the most successful game they had ever made. Late last year, they added upscaling technologies like DLSS 2 (Super Resolution) and AMD FSR 2 alongside in-game real-time ray traced reflections, all of which were flat-out improvements.
As such, I approached this NVIDIA DLSS 3 test believing it to be another slam dunk. Forza Horizon 5 is, after all, notoriously heavy on CPUs due to its large open world environments.
Indeed, the handy benchmark tool built into the game reveals a sizable frame rate boost provided by Frame Generation (DLSS 3). As you can read below, Forza Horizon 5 at max settings (ray tracing included), 4K resolution, DLSS Super Resolution set to Quality, and Frame Generation ended the benchmark with an average of 168 frames per second, a 31.25% improvement over the 128 FPS I got with Frame Generation disabled.
