original OP with some camera measurements:
so i got a casio ex-zr700 which can record 1000fps video at 224x64
original LED method attempt:then i tried to do this with my g100s and managed to destroy the mousedisassembled logitech g3 + led flashlight + wires from the fan of an intel stock cooler + fingernails as wire strippers + lots of packing tape =
currently the problem is that the switch is rather mushy and I can make the flashlight turn on/off without the switch actually actuating
so i got a new g100s and decided to do motion lag measurements by using the dead g100s to hit the new g100s
motion lag measurements
(that means smack the mouse with something and see how long it takes for the screen to respond):
1: barebones love2d program that basically draws a big vertical bar where the mouse is. if the mouse's position changes the color changes.
hardware used here:
sony cpd-g520p CRT, 4770k, asus z87-pro, gtx 460, g100s @ 1000dpi, 500hz without driver, white sheet of paper as mousepad
video recorded with casio ex-zr700 @ 1000fps.
nvidia driver 337.88
love2d with the following code: http://pastebin.com/aa1pgtkp
give or take 1ms for determining when the mouse starts moving.

2. a csgo local server
same stuff as above but with csgo.
opened a really simple custom map. no fps_cap, scoped into a region where the wall meets the sky, set sensitivity to 200, and hidehud 4. all settings verylow/low, 4x msaa, multicore off. the ingame fps was >900. launch options (shouldnt affect anything): -novid -high -tickrate 128 -w 1024 -h 768 -freq 150 -nogammaramp
result: 5,6,6,5,5,5 ms
3. same as (2) but varying a bunch of ingame settings
results: see my posts on page 3. everything is as expected. there are no settings in csgo to worry about. as long the fps is high, the input lag is low.
- 125 vs 500hz mouse
repeat csgo measurements at lower fps
monitor comparisons between crt, vg248qe gsync, and my old crappy viewsonic lcd
test the nvidia driver paranoia with different driver versions, scaling modes, etc..
test gtx 460 vs gtx 970 vs intel (im gonna laugh reallllly hard if intel has the least lag)
asus bios mouse cursor
windows mouse cursor
x11 cursor in linux
wayland cursor in linux
barebones opengl program in linux
some sort of barebones program in windows (would appreciate help here as I really hate using the winapi)
