Here's another pass on my own machine with the current version using the same settings as before.
Specs & Settings
Scenario & Performance
Only a small sample this time because in general I noticed a significant decrease in performance versus v2025.10.6.2584. Thankfully the game open without any hiccups at max graphics with only the 10GB of VRAM but the game is eating about 90% of that on its own to do so. I might try re-installing the older version to double check my numbers.

A quick test of my laptop setup.
Using Solar system.
Specs & Settings
Scenario & Performance
This part is with the RTX 4060 undervolted to the min I can set it which clocks at 1770 MHz and capped at 0.7 volts. It uses 35-45 watts of power.
This is the part with RTX 4060 overclocked. Clocks at 2640 MHz max and uses max 100 watts of power in some areas.

| Scenario | FPS |

| Scenario | FPS |
|---|---|
| Rocket orbiting Earth at 207km looking down at surface | 59-64 (No difference as undervolt interestingly but uses 1.5x more power) |
| Map view above earth looking at the planet | 165 (Vsync) |
| Rocket Splashdown on Earth looking at the horizon | 85-90 (Uses almost 3x more power) |
| Rocket orbiting Jupiter at 2200 km looking down at the clouds | 55-58 (Also uses almost 3x more power) |
Notes
- Based on my analysis, the water and clouds seem to consume the most GPU usage, though I can't understand why there is no difference in FPS at LEO even with overclocking or undervolting.
- Warping in orbit doesn't have any FPS impact, even at the fastest warp speed (x7,776,000). In my opinion, that’s crazy considering the physics calculations are still active.
- Warping in water is a different case, though. Since the craft bounces up and down on the waves, it gets laggier up to 30x speed. However, at 120x and more, physics are no longer calculated, and the FPS returns to normal.
- Performance on the water may vary depending on your location and the direction you are looking.
- The iGPU is bypassed using an external monitor connected directly at my RTX 4060.
- The visual settings are at the limit of what the VRAM can handle. If I were to increase any of them, it would offload to my RAM, and the FPS to drop drastically.
- Overclock/Undervolt settings and FPS readings were monitored using MSI Afterburner with RivaTuner Statistics Server.

cpu ryzen 5800x
ram 32 gb ddr4 3600
gpu 7900xt
vram 20 gb
resolution 4k
version v2025.11.4.2791
textures 4k
shadows 8k
fps 130hz in earth-moon system, got as low as 35 landing on titan. those clouds. both with full solar system loaded.
think that 20 gigs of vram is helping me a lot. game is rock solid stable.
