Upgrade to FSR 4.0.2 and 3.1.5 in ANY Game - S.T.A.L.K.E.R. 2 Guide!

Let’s upgrade FSR to 4.0.2 (RX 9000) and 3.1.5 (older cards) in S.T.A.L.K.E.R. 2 by renaming binaries from the AMD FidelityFX SDK 2.0.0, since DLSS-Swapper isn’t updated yet. Let’s boost your games!

🔧 What you’ll learn:
• Downloading and extracting the FidelityFX SDK
• Renaming binaries to upgrade FSR versions
• Installing the new DLL in S.T.A.L.K.E.R. 2
• Verifying the update with OptiScaler
💡 Pro Tip: Back up your original DLL before overwriting!

Big changes in SDK 2.0.0: FSR 4.0.2 brings ML-based neural rendering, FSR 3.1.5 fixes negative rcas output, and Frame Interpolation 3.1.5 stops crashes from latency and alt-tab deadlocks.
