preset.<\/p>\n<p>If the game still hitches, check the PC around it: overlays, capture tools, GPU drivers, laptop power mode, VRAM pressure, storage speed, and mods.

If frames arrive unevenly, the game can feel choppy even when the FPS counter looks fine.<\/p>\n<\/div>\n<\/div>\n<div data-schema-only=\"false\" class=\"wp-block-aioseo-faq\">\n<h3 class=\"aioseo-faq-block-question\">What is the best FPS cap for Subnautica 2?<\/h3>\n<div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">Start with a 60 FPS cap. If your PC cannot hold 60 smoothly, use 30 FPS instead. A stable cap usually feels better than uncapped FPS bouncing up and down.<\/p>\n<\/div>\n<\/div>\n<div data-schema-only=\"false\" class=\"wp-block-aioseo-faq\">\n<h3 class=\"aioseo-faq-block-question\">Which Subnautica 2 settings should I lower first for FPS drops?<\/h3>\n<div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">Lower Global Illumination, Shadows, Effects, Reflections, Clouds, and Post Processing first. Lower Textures only if your GPU is running out of VRAM.<\/p>\n<\/div>\n<\/div>\n<div data-schema-only=\"false\" class=\"wp-block-aioseo-faq\">\n<h3 class=\"aioseo-faq-block-question\">Should I turn off Motion Blur and Underwater Blur?<\/h3>\n<div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">Yes. Turning both off improves visibility and makes camera movement feel cleaner. It also avoids the smeared underwater look that can make stutter feel worse.<\/p>\n<\/div>\n<\/div>\n<div data-schema-only=\"false\" class=\"wp-block-aioseo-faq\">\n<h3 class=\"aioseo-faq-block-question\">Can DLSS or TSR fix Subnautica 2 FPS drops?<\/h3>\n<div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">DLSS, FSR, or TSR can help if your GPU is overloaded, especially at 1440p or 4K. Start with Quality or Balanced. Performance mode is a last resort because it can look blurry.<\/p>\n<\/div>\n<\/div>\n<div data-schema-only=\"false\" class=\"wp-block-aioseo-faq\">\n<h3 class=\"aioseo-faq-block-question\">Why does Subnautica 2 stutter when I move into new areas?<\/h3>\n<div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">That usually points to asset streaming, VRAM pressure, storage speed, or shader\/cache behavior. Use an SSD, lower textures if VRAM is full, and close background apps.<\/p>\n<\/div>\n<\/div>\n<div data-schema-only=\"false\" class=\"wp-block-aioseo-faq\">\n<h3 class=\"aioseo-faq-block-question\">Are Subnautica 2 performance mods safe?<\/h3>\n<div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">Some config mods can help, but they are optional and can break after Early Access updates. Back up files, read recent comments, avoid random mirrors, and remove mods before troubleshooting crashes.<\/p>\n<\/div>\n<\/div>\n<p><script>(function(){ function ready(fn){ if(document.readyState === 'loading') document.addEventListener('DOMContentLoaded', fn); else fn(); } ready(function(){ var checklist = document.getElementById('sn2sChecklist'); var bar = document.getElementById('sn2sProgress'); var text = document.getElementById('sn2sChecklistText'); function updateChecklist(){ if(!checklist || !bar || !text) return; var boxes = checklist.querySelectorAll('[data-sn2s-points]'); var score = 0; var total = 0; boxes.forEach(function(box){ var points = Number(box.getAttribute('data-sn2s-points') || 0); total += points; if(box.checked) score += points; }); var pct = total ?
