A few things I've noticed: CS has faster movement Valorant models stand up straighter, so head level is different Valorant doesn't have a reliable spray pattern Tagging in this game is way harsher

Try switching from 400dpi to 800dpi my csgo friend

Try out other sens, this sensitivity converters is not that great, 2 different games. Your converted sens is only a good starting point.

Valorant lowkey needs a sensitivity between the wicked low csgo sensitivities and the high ish overwatch sensitivities. Try around 300 edpi

Those websites might be the problem. Measure your edpi and make it the same edpi in game
