Unreal Engine 5’s efficiency points proceed to trigger debate as increasingly builders transfer to Epic Video games’ platform. Whereas the software program’s accessibility and highly effective instruments for 3D creation have seen it to the highest of our decide of the very best sport growth software program, avid gamers complain about stutter, crashes and mangled graphics on lower-spec {hardware} (see our information to the very best video games consoles).Epic Video games CEO Tim Sweeney has addressed the subject in a latest interview. He says it is not all of the software program’s fault however a problem with builders not optimising their video games. It is an opinion that is provoked additional fierce debate.MAJOR WARNING When you’re planning on taking part in Steel Gear Stable Delta:The sport runs terribly, with PS5/XSX rendering 720p-1080p at 30-50FPS in Efficiency modeThe PS5 Professional someway runs worse & seems blurrier regardless of utilizing PSSRAnother disastrous Unreal Engine 5 launch. pic.twitter.com/Lnha48T2C6August 22, 2025As quoted by This Is Recreation, Tim supplied his stance on Unreal Engine 5 efficiency points in a media interview after his keynote at Unreal Fest 2025 in Seoul. His take is that the issue lies in what number of studios method sport growth, leaving optimisation in direction of the top.

“Most builders start by constructing for the highest-end {hardware}, then solely within the remaining levels do they optimize and take a look at for lower-spec units,” he mentioned. “That late-stage method is the important thing motive gamers expertise efficiency issues.”Some devs would possibly say that some platforms are extra conducive to optimisation than others (see our Unreal Engine vs Unity comparability). Tim did go on to recognise that optimisation is not simple, however prompt that ideally it “needs to be applied early in growth, earlier than full-scale content material constructing begins”.He mentioned Epic is now engaged on paring two important approaches to handle the difficulty and to encourage higher optimisation in Unreal Engine 5. “One is to strengthen help for Unreal Engine,” he mentioned. ”Since optimization requires vital guide labor, we plan to supply automated optimization options for varied units, enabling builders to work sooner and extra simply””One other method is to strengthen developer coaching,” he mentioned. “Along with offering coaching on the general testing and optimization course of, it is essential to boost consciousness that optimization ought to happen early. If vital, our engineers can instantly intervene to boost consciousness of optimization strategies and supply technical help”.Each day design information, evaluations, how-tos and extra, as picked by the editors.Tim’s newest feedback on Unreal Engine 5’s efficiency points have provoked combined responses amongst builders and avid gamers alike. ”He is completely right,” one particular person wrote on X. “Simply because your studio has an array of 5090’s does not imply that you must make all the sport primarily based on the {hardware} you are working with.”“Optimisation has been a large number lately, they overlook that [the] majority of the avid gamers nonetheless use low-end to midrange PCs,” one other particular person wrote in settlement. “Nvidia will ship their highest finish {hardware} simply to get devs to make use of their tech, that is essentially the most revealing issue,” one other particular person prompt, whereas others prompt that indie video games usually run higher than AAA titles as a result of the devs are “pressured to optimize from day one”.However others disagreed. “But they did not optimize Unreal Engine 5 itself early as all the focus was slapping in resource-heavy options all whereas choking CPU effectivity by making the engine closely single threaded,” one particular person claimed. “To not point out the steadiness concern of the engine crashing throughout sport growth”.“You may’t blame all of the devs utilizing your engine,” one other particular person argued. ”This exhibits your product has flaws….repair them, streamline and optimise”.The talk is not prone to go away quickly, with the discharge of Steel Gear Stable Delta: Snake Eater mentioning acquainted points. However even when it is generally unstable, Unreal Engine 5 is very purposeful, and increasingly builders are selecting to make use of the platform as an alternative of spending money and time creating their very own sport engine.What do you assume? Is the difficulty with the platform itself, or do greater studios maybe must keep in mind that not all of their clients have the very best graphics playing cards?
