The PC and PS5 console-exclusive Lost Soul Aside only released today, August 29, but it's already sitting on a 'Mixed' Steam review score from 300+ players, many of whom have reported issues with performance and optimization.Developer Ultizero Games was quick to respond, assuring players in a statement that it had "received your feedback regarding the performance of certain cutscenes in the prologue of Lost Soul Aside," and was "actively working on optimizations.""Currently, some of these cutscenes are pre-rendered 4K/30fps videos, which may cause occasional stuttering during playback," the team explained. "We sincerely apologize for any inconvenience this may have caused and appreciate your understanding."The Lost Soul Aside team is actively working on optimizations, and future updates will address this to deliver a smoother gameplay experience. Thank you for your continued support and patience!"Notably, no time frame was provided, so it's unclear when, exactly, players can expect a fix. In the meantime, Steam continues to fill up with reviews from unhappy players."I’ve completed the prologue of Lost Soul Aside, and in its current state I can’t recommend this game," said one player, while another added: "I thought movement looked jerky because of frame drops but the walking actually just looks like that lmao. Walking and the camera are so bad it's honestly impressive." "I'm only three hours in but I’m really torn on this game," commented another Steam reviewer. "On one hand, the visuals are top-notch and the combat is decent (a tier below Stellar Blade, imo). These were the two things that had been consistently teased and promised, and Yang Bing and his studio finally delivered on those aspects. Everything else is kind of a mess."Lost Soul Aside is a stylish single-player action-adventure RPG in which you battle dimensional invaders while trying to save your sister. It was initially expected to release in May but after roughly a decade in development, Lost Soul Aside was delayed three months from May 30 to August 29.Vikki Blake is a reporter for IGN, as well as a critic, columnist, and consultant with 15+ years experience working with some of the world's biggest gaming sites and publications.
