AMD's latest driver has made their "Anti-Lag/+" feature available for CS2, which is implemented by detouring engine dll functions. If you are an AMD customer and play CS2, DO NOT ENABLE ANTI-LAG/+; any tampering with CS code will result in a VAC ban. Once AMD ships an update we can do the work of identifying affected users and reversing their ban. @AMD

Every conservative state should put into code that Jesus Christ is King and dedicate their state to Him. Force RINOs to say no to Jesus and then brutalize them in elections. We need a government of Christians, not fakers.

Concert tickets are hard enough to get, you shouldn’t have to pay surprise service fees on top of that. My Administration is working to crack down on those junk fees, so you know what you are paying for up front.

We were extra active on Twitter this morning, which means there's a CS2 update. Today we're adding Casual, swapping out Mirage for Nuke and Office, making adjustments to audio, fixing the slow crouch bug, addressing bunny hopping and more! And you can now inspect grenades.

I don't see the dilemma? Just let them pay for the data like everybody else who needs to use copyrighted data for commercial purposes.
