DressX's AR wearable technology for virtual fashion NFTs faces several bottlenecks. Limited interoperability restricts digital garments' use across diverse metaverse platforms, confining their utility. Current AR rendering often lacks realism, with digital overlays appearing artificial, especially in dynamic settings. High computational demands for real-time AR try-ons strain mobile devices, leading to lag or poor performance. Blockchain integration for NFT authentication, while secure, introduces latency and complexity, hindering seamless user experiences. Additionally, the absence of widespread AR hardware, like advanced glasses, limits mass adoption. Scalability issues arise from processing large volumes of 3D assets, impacting accessibility. Overcoming these requires enhanced cross-platform standards, optimized rendering algorithms, and broader hardware support to fully realize DressX's vision of sustainable, expressive digital fashion.
