ENGINEERING ARCHITECTURE
The 3-Surface Native Overlay Runtime
Unlike legacy overlays that wrap the entire game in a heavy hook or hijack input buffers, SysCubes separates presentation into three decoupled hardware surfaces:
Surface 01
Passive Transparent HUD
Borderless, zero-alpha surface pinned above the game window using native DWM composition. Handles pass-through routing with sub-0.2ms overhead.
Surface 02
Overlay Controls Toolbar
Subtle unobtrusive trigger layer docked to your screen edge for rapid profile switching and quick hotkey status feedback.
Surface 03
Interactive State Canvas
Dedicated isolated input plane that wakes only when toggled by your hotkey, allowing full drag-and-drop widget editing before gracefully yielding focus.

FREQUENTLY ASKED QUESTIONS
Questions About Custom In-Game Overlays
Everything you need to know about setting up and customizing your HUD.
Will this overlay block my mouse clicks during intense gunfights?
No. In Click-Through mode, SysCubes enables native OS pass-through. All mouse events bypass the overlay window completely and route directly to the game engine with sub-0.2ms latency, ensuring your crosshair and combat inputs are never interrupted.
Does the SysCubes overlay cause FPS drops or micro-stutters?
No. The overlay rendering loop is completely decoupled from your game's Direct3D or Vulkan pipeline. Benchmark measurements show 0.0% frame-rate reduction and zero frame-time variance across tested competitive titles.
Is SysCubes safe with Riot Vanguard, BattlEye, and Easy Anti-Cheat?
Yes. SysCubes never injects code into game memory, modifies executable binaries, or reads protected memory offsets. It utilizes standard Windows DWM composition layers and the officially whitelisted Overwolf overlay platform, keeping your account 100% safe from bans.
Can I set up different widget layouts for different games?
Yes. SysCubes features automatic process detection. When you launch a title like Counter-Strike 2, Valorant, or League of Legends, your custom HUD layout tailored for that specific game loads instantly without manual profile switching.
