Motion blur in Halo: Campaign Evolved has been singled out for its exceptionally poor implementation, particularly affecting gameplay at frame rates between 30 and 60 frames per second. According to reports, this effect can turn the game into a "nightmare of blurred frames," making it difficult to discern action on screen, especially during rapid head movements or intense combat scenarios.
The visual degradation is so pronounced that it can render gameplay "genuinely hard to understand what's happening on screen." While performance improvements can be made by increasing the frame rate to around 100 fps, potentially through upscaling or resolution drops, the motion blur remains a noticeable distraction at best.
PC Gamer's testing indicated that the game's graphics settings have a limited impact on the overall visual presentation, with only minor changes to lighting and shadows being apparent. Technologies like Temporal Super Resolution (TSR) showed negligible differences across various gaming PCs. However, TSR did appear to offer an uplift on the Asus ROG Xbox Ally X, a detail that has been flagged for Microsoft.
For players seeking to boost frame rates, the choice of upscaling technology is crucial. NVIDIA users are recommended to use DLSS, which offers both performance gains and superior visual quality compared to AMD's FidelityFX Super Resolution (FSR) 3.0. While FSR 3.0 can provide a significant FPS boost, its lower settings can result in a "messy and distorted" image. DLSS at medium or ultra settings reportedly delivers better performance and a more refined look than FSR counterparts.
Owners of AMD GPUs, which do not support DLSS, may find FSR to be a viable alternative. On an RX 9070, FSR was observed to provide distinct performance improvements with strong visual fidelity. In the absence of DLSS and with TSR proving ineffective, FSR remains a solid option.
Users experiencing performance issues are advised to experiment with these settings and consider disabling other potentially distracting effects like screen shake, especially given the prevalence of grenades in the game. The overall recommendation is to leverage higher graphical settings if the system can support them, avoiding configurations that combine low settings with unwanted visual effects like motion blur and screen shake.
