After some investigation, I discovered that the <strong>Read\/Write Enabled<\/strong> option on imported models was the culprit. In Unity 5.6, this setting was enabled by default, which caused Unity to keep a duplicate copy of each model in memory, significantly increasing the project\u2019s memory usage.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"677\" height=\"1020\" src=\"https:\/\/vh18545.vh.net.pl\/wp-content\/uploads\/2024\/11\/obraz.png\" alt=\"\" class=\"wp-image-270\" srcset=\"https:\/\/vh18545.vh.net.pl\/wp-content\/uploads\/2024\/11\/obraz.png 677w, https:\/\/vh18545.vh.net.pl\/wp-content\/uploads\/2024\/11\/obraz-199x300.png 199w\" sizes=\"auto, (max-width: 677px) 100vw, 677px\" \/><figcaption class=\"wp-element-caption\">Screenshot of Unity 5.6 with Read\/Write Enabled option checked<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">In this project, no one had reviewed the import settings after the upgrade, so the unnecessary memory usage went undetected. After switching to Unity 2022, disabling <strong>Read\/Write <\/strong>on models resolved the issue, leading to a substantial reduction in memory consumption.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"758\" height=\"1000\" src=\"https:\/\/vh18545.vh.net.pl\/wp-content\/uploads\/2024\/11\/obraz-1.png\" alt=\"\" class=\"wp-image-271\" srcset=\"https:\/\/vh18545.vh.net.pl\/wp-content\/uploads\/2024\/11\/obraz-1.png 758w, https:\/\/vh18545.vh.net.pl\/wp-content\/uploads\/2024\/11\/obraz-1-227x300.png 227w\" sizes=\"auto, (max-width: 758px) 100vw, 758px\" \/><figcaption class=\"wp-element-caption\">Screenshot of Unity 2022 with Read\/Write Enabled unchecked<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Optimizing Import Settings for Better Performance<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To make sure your game performs optimally, always review the import settings for each asset. Here are some key settings to pay attention to:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Textures<\/strong>: Check resolution and compression settings. Large, uncompressed textures can drain memory and slow down performance, especially on mobile or VR.<\/li>\n\n\n\n<li><strong>Models<\/strong>: Disable <strong>Read\/Write <\/strong>on models unless you specifically need it for runtime modifications. Additionally, consider reducing the polygon count of complex 3D models in modeling software to save memory.<\/li>\n\n\n\n<li><strong>Audio<\/strong>: Use compressed audio formats for sound effects to reduce file sizes without compromising quality.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Always review import settings when adding new assets or upgrading Unity versions. Optimized import settings help keep memory usage in check, boost performance, and prevent unexpected issues, ensuring a smoother experience for your client and end users in Unity.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction When I upgraded my client&#8217;s project from Unity 5.6 to Unity 2022, I noticed a surprising increase in memory usage.
