FPS drop of ARC 140T

[merrymarry]

Hi, I recently bought a brand new laptop ASUS zenbook duo (UX8406CA) which comes with intel iGPU ATC 140T.

I tried to play several games with this laptop, and it really dissapoints me.

While playing basic 3D games such as Overwatch2 the FPS frequently drops and the game stutters periodically, which makes it impossible to enjoy the game.

Even though I deleted the driver and installed the latest driver (which was released on 03.07.2025), the problem persists.

Anyone with an idea?

I seems have some way to fix it: half it from reddit but I cant find it now.

I'm on UX3405CA, 285H with 140T.

Goes: Exploit Protection(windowsdefender://exploitprotection/),

Or at Windows Settings -> Privacy & security -> Windows Security Center -> App and Browser Control -> Exploit Protection

From reddit, it just turn off the Control flow guard (CFG) for apps or games.

But it not works for me, so i turn off ALL In System Tab but with Data Execution Prevention (DEP) on.

See will this help, for me, i got no stuttering in Civ6 benchmark and other game play.

I cap the fps to 100 of 120Hz screen, with nearly 100 fps smooth.

Plus it could not the intel issue, i got amd 8840u with 780m also got same issue, and fixed in same way.
