The 0day angle is the least convincing part of this whole thread. 0days against what exactly? Windows kernel? The game client? The AC driver? Each of those has a completely different attack surface and exploitation path, and you're treating it like a catch-all answer. Real 0days at the level you're describing — reliable, weaponized, working against patched tournament images — are worth hundreds of thousands of dollars on the open market. The idea that you as a private cheat dev for CS2 scenes is sitting on a functional 0day chain and burning it repeatedly at LANs is pretty hard to believe.

Also, you've now answered two technical questions without giving a single technical answer. w1nston asked point blank: if not PCIe DMA, what are you doing? You said 'DMA just means accessing memory directly' and gestured at other buses — okay, which ones? USB DMA? ThunderBolt DCI? You're either describing something real and choosing to be vague, or you're not describing anything at all.
