If the DLSS Frame Generation option sits greyed out in AION 2, you\u2019re probably about to reinstall your driver, verify game files, and blame Nvidia<\/a>. Stop. The option is almost never broken. It\u2019s locked because a chain of system-level prerequisites isn\u2019t aligned \u2014 and you can fix that chain in about twenty minutes without touching your Windows<\/a> installation.<\/p>\n

To get straight to the answer: enable Hardware-Accelerated GPU Scheduling in Windows, restart your PC, disable G-Sync and enable V-Sync in the NVIDIA Control Panel, and relaunch AION 2 in fullscreen mode. That sequence resolves the majority of greyed-out cases. If it doesn\u2019t, you move to driver-level overrides and a monitor configuration check.<\/p>\n

The Lock Is Not the Game\u2019s Fault<\/h2>\n

DLSS Frame Generation works by inserting synthesized frames between rendered ones. That process needs a specific combination of GPU scheduling, sync behavior, and driver hooks. When one of those pieces is missing, the engine simply hides the option. AION 2 doesn\u2019t grey it out because the feature is unsupported \u2014 Nvidia has already shipped a day-1 Game Ready driver with DLSS 4.5 super resolution and multi-frame generation support for global AION 2. The option is present in the menu. It\u2019s just disabled until the environment is correct.<\/p>\n

The most common culprit by far is Hardware-Accelerated GPU Scheduling, or HAGS<\/a>. Frame generation relies on it to bypass part of the CPU scheduling bottleneck. On a stock Windows install, HAGS is often off, especially if you\u2019ve disabled it for an older game. The fix isn\u2019t complicated, but it requires a restart.<\/p>\n

One counterargument: \u201cIt\u2019s a game bug, look at all the forum posts.\u201d Fair enough. There are always forum posts. But the same greyed-out symptom across thousands of Unreal Engine<\/a> titles \u2014 from WARDOGS to AION 2 \u2014 points in one direction. If the feature were genuinely broken, a clean driver install wouldn\u2019t unlock it. The NVIDIA app\u2019s override settings wouldn\u2019t change anything either. They do. That alone kills the \u201cbug\u201d theory.<\/p>\n

Step 1: Turn On Hardware-Accelerated GPU Scheduling<\/h2>\n

Open the Windows search bar, type Graphics Settings, and go to the advanced graphics settings section. Toggle Hardware-Accelerated GPU Scheduling to On. Restart your PC. Do not skip the restart \u2014 the setting doesn\u2019t apply otherwise.<\/p>\n

After the restart, check the in-game option again. If that alone unlocks it, you\u2019re done. If not, move to the sync settings.<\/p>\n

Step 2: Disable G-Sync, Enable V-Sync in NVIDIA Control Panel<\/h2>\n

Launch the NVIDIA Control Panel and select Manage 3D Settings. Find AION 2 in the program list. If it isn\u2019t there, add it manually. Set Vertical Sync to On.<\/p>\n

Here\u2019s the part that surprises people: you also need to disable G-Sync for the game. This applies even if you\u2019re on an RTX 5000-series laptop with G-Sync enabled on the display. Frame generation and G-Sync conflict when the driver tries to keep the monitor\u2019s refresh rate in sync with synthesized frames. The result is a greyed-out toggle.<\/p>\n

So: set G-Sync off for AION 2, V-Sync on, apply, then restart the game. Switch the game to fullscreen mode. Borderless windowed can still work, but fullscreen is the most reliable.<\/p>\n

Step 3: If Still Greyed Out, Override the Driver<\/h2>\n

Nvidia\u2019s newer app lets you override DLSS settings at the driver level. Open the NVIDIA App, go to Graphics, select AION 2, and look for DLSS Override Frame Generation. If you see an Edit option, set it to \u201cUse 3D app settings,\u201d apply, and retry. If the option still refuses to appear in-game, try \u201cRecommended,\u201d or manually set a custom preset like A or B for frame generation.<\/p>\n

The same menu has a Smooth Motion toggle. If it\u2019s off, turn it on. Nvidia\u2019s smooth motion can force an interpolation path that makes the in-game toggle activate.<\/p>\n

Step 4: Attack the Monitor and Resolution Variables<\/h2>\n

A surprising number of greyed-out cases trace back to display configuration, not GPUs.<\/p>\n
