Doubts about subpixel sensitivity improvement:
knowing than mainly pixel structure is 3 subpixels RGB (vertical rectangles), not seems a "stable" solution, because only will work horizontaly, not verticaly. So when move mouse very slow "pixel at pixel", horizontal result in 3x smoother mov with this improvement, but vertical continue with default pixel jumps. Diagonal is a mix. And this unbalanced axis sens not sound very good for get phisical mouse mov = crosshair mov independently of the direction.
Moreover, there are screens with others subpixel structures, BGR, or horizontal rectangles stacked vertically, or RGBW in recent LG OLED CX TV, making this improvement more hard to implement massively. But even programming detection and optimization to all structures, axis unbalanced is here, one axis fine, other not.
Seems more reliable just double screen resolution, 1080@2160, increased 2x the smoothness in both axis, with 1.0 sensi, and dpi at the player preference, that should be configured at hardware level at one by one dpi steps. Not 50 or 100 steps.
Thanks for work on 8K improvement, is a very big jump. Poll affinity optimization to one core, right from driver, sound amazing as well, and easy to all players that not know about these system tweaks. I did test with the affinity tool that NDUS link here, and others, from years ago in the 2-core CPU days and Windows XP, with good results in 1 core 3D games, like Return to Castle Wolfenstein (Quake3 engine), more smooth mov, less audio issues, and better frametime stability with VSync On. Yeah, worth it !
Razer plan restore the old "Drift Control" interpolation feature ? not activated by default obviously, is not intended for gaming. Only have one way to optionaly activate it.
I still have two units of the good old Deathadder 3G. This mouse has two firmwares 1.39 NDC (No Drift Control) and 1.40 DC with Drift Control directly done by the hardware. To play i used NDC, but for desktop tasks i prefer DC, so i need change the mouses. Unfortunately, after Deathadder 3G i not see any Razer mouse with this feature, nor in firmware, nor in drivers. Now i use for play more modern Razer mouses, but continue with Deathadder 3G for desktop to enjoy DC, and i would like to end this hassle of changing them.
Would be great if can be restored, in order to increase the mouse versatility beyond gaming. SteelSeries do it, and interpolation can be customized, is named "FreeMove", but they not have sensitivity per axis configuration, so i'm not interested.
Sorry for off-topic !
