[b]Statement :[/b] The issue is related to AVX (Advanced Vector Extensions) and AES-NI trying to force into the non supported CPU's to register instructions on data, process isn't working due to runtime error for exception illegal instruction. Not all CPU's support AVX. Generally, CPU's with the commercial denomination "Core i3/i5/i7/i9" support them, whereas "Pentium" and "Celeron" CPU's don't. Any CPU's before Sandy Bridge (2nd generation) 2011 by Intel won't support AVX technology. If you did not understand anything past this point, it does not matter. I don't understand computer code either. What you must understand is the watery bulbous meatbags working at Bungo are at fault, I suppose I should not call them such, not to refer to them by their meatbag status in the future. [b]Analysis :[/b] Additionally, If you get an instruction exception error of the AES-NI extension set in your dxDiag logs or in your crash logs AppData\Local\Temp\Destiny 2\crash_folder\pc_x64 then you most likely can't launch the game because of non supported AES-NI x86 instruction set architecture for microprocessors from Intel and AMD before 2008. [b]Observation :[/b] For instance, a old 2008 Bloomfield i7-950 CPU will get an AES-NI extension set error like "AESKEYGENASSIST" in the crash logs because it doesn't support AES-NI instruction sets. Some newer processors like the (9th and 10th generation) do not support AES-NI. [b]Query :[/b] If your CPU is overclocked and you have AVX by setting "CpusupportsAVX" to 0, you will get an instruction set error. Try turning AVX offset to 2 which puts those instructions back on. Don't mess with any overclocking settings, if you don't know what to do, you could potentially overheat your processor and cause severe computer malfunction, I do not suggest to take this course of action as it would be bad for your computer. [b]Commentary[/b] : The liquidious bipedal fleshbags working at Bungo, need to disable the silent force check for AVX or people with older or newer CPU technology that don't support the above instruction sets won't be able to launch the game on steam. [b]Temporary fix[/b] : If you know how to access your bios, switch your mobo AES-NI to ENABLE under advanced settings CPU configuration. Save your bios settings and restart your computer. [b]Explanation[/b] : If your mobo doesn't have AVX or AES-NI support like me then you need to wait for the organic meatbags working at Bungo to implement a fix because A) your processor is old or B) you have a newer generation processor with no AVX or AES-NI support. A CPU which does not support AVX or AES-NI code can of course not run AES-NI and AVX-specific program written with AVX or AES-NI in mind on an incompatible x86 CPU: it simply doesn't recognize them. That would be the equivalent of trying to start a car engine with organic matter as fuel.
