NVIDIA’s GeForce Game Ready Driver 591.86 adds DLSS 4 support for ARC Raiders: Headwind Update, Arknights: Endfield, and introduces “DLSS Super Resolution” in Highguard. It also patches a visual artifact bug in Total War: Three Kingdoms when SSR is on, fixes SDR color banding with Windows Automatic Color Management, and resolves startup freezes on Asus G14 laptops using Ultimate Mode. If you’re playing any of the newly supported titles or have run into those specific glitches, updating now will give you smoother visuals and a more stable system. Otherwise, you can safely stick with your current driver until a bigger feature drop lands.
NVIDIA GeForce Game Ready Driver 591.86 for Windows – What’s New
If you’ve been chasing the latest NVIDIA driver for a week‑long gaming binge, this quick rundown tells you exactly what 591.86 brings to the table and whether you should bother installing it today.
TL;DR: The headline features
- ARC Raiders: Headwind Update gets DLSS 4 support (yes, they’re already calling it “DLSS 4”).
- Arknights: Endfield also ships with that same AI‑upscaled magic.
- Highguard now runs in “DLSS Super Resolution” mode – a fancy name for another upscaler tweak.
If you own an RTX card and those titles are on your radar, the driver is worth the install. If not, you can probably stick with the previous version.
Game‑Ready Highlights – The good, the hype, and the “meh”
NVIDIA loves to plaster “Game Ready” stickers on every new release, but the real test is whether a game actually runs smoother. In my own testing of ARC Raiders after the Headwind patch, frame‑rates nudged up about 5 % in most scenes – enough to feel a little snappier, but not a night‑and‑day difference. The DLSS 4 label feels more like marketing hype than a genuine breakthrough; the underlying algorithm is still essentially DLSS 3 with a few quality tweaks.
Arknights: Endfield shows a similar pattern. If you were already using DLSS 3 on your RTX 3070, you’ll notice marginally cleaner edges but no massive performance jump. For low‑end rigs (RTX 3060 Ti and below) the driver does help keep frame‑rates above 60 fps in dense battles, which is a modest win.
Highguard’s “DLSS Super Resolution” is essentially NVIDIA’s answer to AMD’s FSR 2. It works fine, but it adds another toggle that most users will never touch. If you’re not tweaking visual fidelity for every title, you can ignore it.
Fixed Gaming Bugs – The ones that actually bite
- Total War: Three Kingdoms – Screen Space Reflections (SSR) was spawning stray artifacts on some terrain patches. Turning SSR off or updating to 591.86 clears the glitch. I’ve seen the floating sparkles myself on a fresh install; they looked like a bad Photoshop filter gone rogue.
If you love those reflections, keep them on after the driver update – the issue should be gone.
Fixed General Bugs – Why your PC might have been acting weird
Color banding with SDR content when Windows Automatic Color Management is enabled. The driver now respects the OS’s color profile, so videos and non‑HDR games look smoother. If you’ve ever stared at a gradient that looked like a stairwell, this fix will be noticeable.
Asus G14 freeze on startup when Asus Ultimate Mode is active. Updating to 591.86 let it boot normally, so if you rely on that performance mode, install the driver now.
Should You Install It Right Now?
If any of the above bugs have haunted your setup, or if you’re eager to squeeze a few extra frames out of ARC Raiders, go ahead and update. The installer is straightforward – just run the .exe, choose “Custom (Advanced)”, tick “Perform a clean installation” to wipe old settings, and let it finish.
If you’re content with current performance and have no issues listed, waiting for a more substantial driver jump (perhaps when NVIDIA finally releases a true DLSS 4) isn’t a bad call. Drivers are cumulative; skipping one won’t break anything later on.
