The RX 7600 can now load Forza Horizon 6 in about 4 seconds instead of nearly 90 seconds, according to a test published by WCCFTech. The jump doesn't come from a new GPU. It comes from the way Microsoft delivers precompiled shaders at the moment a game is installed. For PC gamers, the most obvious benefits are a shorter wait the first time you launch a game and less stuttering when the game has to compile shaders on the fly. It is the kind of optimization you won't find on a spec sheet, but it directly affects how a game feels to play.
Why can the RX 7600 load Forza Horizon 6 so much faster?
According to Microsoft's DirectX blog, the 4-second result was measured on a system with a Radeon RX 7600 and a Ryzen 7 5800, which works out to a wait time roughly 95% shorter. Advanced Shader Delivery works by shipping shaders that have already been prepared for the exact hardware, rather than letting the user's PC compile nearly all of them on the first run. When that heavy work is moved ahead of the play stage, the game starts faster and shader stutter drops as well.
The practical significance is that many demanding games aren't slow only because of the storage drive or CPU. They also have to build a set of shaders that matches the specific GPU and driver in use. In a racing or open-world game like Forza Horizon 6, this step often shows up as a long loading screen or a few short hitches right after you start playing. If publishers deliver properly prepared shaders in advance, a PC can feel smoother from the first minute without any hardware upgrade. This is especially notable for open-world games that change scenes frequently, where even a few small stutters are enough to spoil the feeling of driving or taking in the scenery at high speed.
The key caveat is that this is still a public preview. To turn the feature on, you need Windows 11 24H2, Xbox Gaming Services 37.113.11003.0 or later, enrollment in the PC Gaming Preview through the Xbox Insider Hub, an AMD RDNA 3, RDNA 3.5 or RDNA 4 GPU, and Adrenalin 26.5.2 drivers or later. As a result, not every game store or every PC game benefits right now. In other words, this is still a conditional testing phase, but it shows that the RX 7600 and other midrange GPUs can still be improved through software instead of just waiting for new hardware.
What do PC gamers and builders gain from shader optimization?
If you've been following the recent changes in Shader Model 6.10, you can see Microsoft pushing in a clear direction: reduce the work that happens on the user's machine and do more of the preparation on the platform and developer side. For PC builders, this matters because it helps separate real hardware limits from delays caused by an unoptimized software pipeline. A midrange card like the RX 7600 doesn't turn into a high-end card after a single update, but the experience can change noticeably if the startup wait and small stutters are tackled at the right points.
Looking at the bigger picture, this also continues the story of Windows running games more smoothly than SteamOS, in which real-world performance depends more and more on how the operating system and graphics toolset work together with the game.
| Category | Before Advanced Shader Delivery | With ASD | Practical meaning |
|---|---|---|---|
| First game launch | About 90 seconds | About 4 seconds | Noticeably faster entry into the game |
| Shader compilation | Happens on the user's PC | Prepared in advance when the game is installed | Less load on the CPU and driver at startup |
| Smoothness early in a session | Short stutters are likely | Less shader stutter | More stable experience in new scenes |
| Scope of support | Depends on how the game handles legacy shaders | Currently limited by platform and hardware | Not yet a general solution for all PC gaming |
What makes this technology worthwhile is that it improves the experience without forcing anyone to replace an entire system. With new graphics cards getting more expensive, any optimization that makes a midrange GPU wait less and stutter less has real value. For the RX 7600 running Forza Horizon 6 specifically, the 4-second figure shows that software still has plenty of room to improve everyday gameplay.
