Valve’s new VRAM optimization is drawing attention after early tests suggested that it can unlock clear gains on graphics cards with only 4 GB of video memory. The strongest result came from Alan Wake II, where performance reportedly climbed from 14 FPS to 41 FPS when the feature was enabled.
The early numbers matter because many lower-end GPUs still struggle less with raw compute power than with memory limits. On systems where VRAM fills up quickly, a software-level improvement to memory handling can matter more than a simple graphics preset change.
Early testing on a modest gaming setup
The first public test was carried out by YouTuber NJ Tech on CatchyOS, using the “Install GPU Boosters” option to activate the tweak. The feature is tied to work by Valve Linux engineer Natalie Vock, and the test setup used an AMD Radeon RX 6500 XT 4 GB, 16 GB of DDR4 RAM, and a Ryzen 5 5600X with its stock cooler.
That configuration reflects a familiar budget-conscious PC class, especially for 1080p gaming. In that segment, the GPU may still have enough core capability for basic rendering, but limited VRAM often becomes the main bottleneck.
Alan Wake II shows the clearest benefit
Among the games tested, Alan Wake II posted the most dramatic improvement. Running at 1080p on Low settings with FSR 2 set to Quality mode, the game moved from an average of 14 FPS to 41 FPS after the VRAM optimization was turned on.
The 1% low result also improved meaningfully, rising from 12 FPS to 28 FPS. That is important because steadier frame pacing can matter as much as the average frame rate, especially in games that become unstable when memory pressure rises.
Other games improved, but not in the same way
Resident Evil Requiem also benefited from the feature in the same test environment. At 1080p with the lowest visual settings and upscaling pushed to the maximum level, average performance increased from 67 FPS to 78 FPS.
Its 1% low figure rose even more sharply, from 36 FPS to 56 FPS. That points to more consistent gameplay under load, even if the gain was not as dramatic as the result seen in Alan Wake II.
Silent Hill F, by contrast, showed only a small change. At Full HD with low settings and Temporal Anti-Aliasing enabled, the average frame rate moved from 47 FPS to 50 FPS, while the 1% low increased by just 1 FPS.
Not every title reacted the same way
Several other games did not show any major uplift in the available test results. The list included Crimson Desert, Cyberpunk 2077, Hogwarts Legacy, Death Stranding, and Spider-Man 2.
That does not automatically mean the optimization has little value. It may simply mean that some games are less sensitive to VRAM handling, or that the testing conditions were not demanding enough to expose a larger difference.
Why the result matters for 4 GB GPU users
The early findings are especially relevant for players using older or lower-cost GPUs with 4 GB of VRAM. On cards in this class, memory limits often create more visible problems than the chip’s raw rendering ability.
For that reason, Valve’s approach could extend the useful life of some aging hardware through software rather than new hardware. The effect is unlikely to be universal, but the data suggests that the feature can make a real difference in games that are heavily constrained by video memory.
For Linux gaming users and anyone still relying on a Radeon RX 6500 XT-style setup, the most important takeaway is simple: the results vary by game, but the early signs are strong enough to keep the feature on the radar, especially for 1080p play on GPUs with limited VRAM.
