Star Citizen’s Planet Tech V5 Nyx I test shows richer biomes, unfinished technical work

Star Citizen’s closed Evocati technical preview is testing the first explorable version of Nyx I using Planet Tech V5, also known as Genesis. Community accounts describe a sparsely populated test environment built to evaluate planetary terrain generation, rendering, streaming and performance rather than deliver a gameplay-ready planet.

Nyx I currently has no points of interest, missions, NPCs or wildlife, according to testers. Reports also say harvestable plants are absent. The limited scope has enabled participants to traverse terrain and test vehicles while assessing how the new system handles detailed landscapes, asset loading and client and server performance.

Forests, wetlands, oceans and mountains

Accounts from the preview describe grasslands, deciduous forests, wetlands and swamps, large lakes, oceans, island chains, rocky ridges and snow-covered mountains. Testers have particularly highlighted denser forests, varied tree heights and foliage that reacts to wind, while some say the planet’s landscapes broadly resemble the mountainous and watery environments previously shown by Cloud Imperium Games.

Water is another visible part of the build. Community reports describe ripples and foam effects when players move through it, as well as rain, clouds and puddles in some conditions. Testers have nevertheless noted that swamp areas appear less developed than promotional footage, citing clear water and a lack of debris or muddy detail.

The preview also appears to retain resource rocks that are integrated into terrain, though players report no clear in-game tool for identifying biomes or reliably locating particular mineral types. That leaves the resource-placement system difficult to assess as gameplay in the otherwise empty test.

Technical test exposes streaming and visual issues

The focus on traversal has also exposed unfinished elements. Testers have reported level-of-detail pop-in during flight and when approaching the surface, along with abrupt object changes, rough biome borders and visible terrain seams. Some descriptions cite pixelated transitions between snow and grass, inconsistent foliage density, repeating terrain patterns, and objects that float, clip or shift position at distance.

Community coverage also points to instability in the work-in-progress build, including server-performance problems, crashes and quantum-travel issues. These reports are anecdotal and come from a closed technical environment, so they do not indicate how a public version would perform.

Several observers have compared the build with earlier CitizenCon footage, saying the test is visibly less dense and polished. That gap is unsurprising for a preview intended to gather performance and rendering feedback, but it has prompted skepticism over how soon the technology and accompanying gameplay features might reach the wider game.

Vulkan-only build shifts emphasis to GPU and VRAM

Planet Tech V5 is Vulkan-only in this testing phase. Tester accounts suggest that Vulkan can reduce CPU pressure and distribute work more efficiently across processor cores, while placing greater demand on graphics hardware and video memory. Community assessments have warned that 8GB graphics cards may be more likely to run into memory limits, though Cloud Imperium Games has not published new V5-specific requirements.

Results vary significantly by setup and scenario. One tester using a high-end water-cooled PC reported roughly 70 frames per second at 1440p and about 30 fps while using a 4K virtual-reality configuration. Other testers have described frame-rate drops during fast, low-altitude flight despite stronger performance while exploring on foot.

The preview’s lack of missions and locations means its performance findings are not directly comparable with a fully populated Star Citizen release. Still, the Nyx I test offers an early indication of Genesis’ goals: more detailed planetary biomes and natural environmental scattering, with the remaining work centered on visual transitions, stability and optimization before the system can support broader gameplay.
