Been messing with an external project for CS2 and ran into the classic visual desync issue that drives everyone crazy during development.
I’m currently running a WinForms GDI+ layered window for the overlay. The problem is simple but annoying: the ESP elements shake and jitter like hell whenever I flick the mouse or move fast. I’ve ruled out basic rendering lag because a static red dot at screen center stays rock solid — so GDI/the window itself isn't the bottleneck. It’s strictly the WorldToScreen projection lagging behind.
The Setup:
Even when I try to sync the RPM calls in a single data block, the jitter persists. My working theory is that the overlay is reading the ViewMatrix at a completely different time than the game engine is actually rendering the frame, leading to a permanent mismatch between where the enemy is on your screen and where the ESP thinks they are.
Is this just the hard limit for external overlays? Some people swear by using a DirectX overlay to fix the refresh rate mismatch, while others mention better synchronization techniques or even predicting the viewmatrix based on delta time.
Possible fixes I'm considering:
While others are catching bans using public internal pastes with dirty hooks, keeping it external is definitely the play for longevity, but the visual polish just isn't there yet.
anyone solved this without going internal?

The Setup:
- External read thread pulling ViewMatrix, PlayerPos, and ViewAngles.
- WinForms GDI+ Layered Window for drawing.
- Calculation for W2S performed in the overlay thread.

Code:
// Typical W2S check
float w = matrix[3][0] * pos.x + matrix[3][1] * pos.y + matrix[3][2] * pos.z + matrix[3][3];
if (w < 0.01f) return false;

Possible fixes I'm considering:
- Moving from GDI+ to a proper SlimDX or SharpDX wrapper.
- Overlay hijacking (e.g., Discord or NVIDIA) to see if the refresh sync is better.
- Implementing a basic interpolation logic for the coordinates.
