Recommended Driver Update: AMD 9950X, RTX 4090 [NVIDIA Studio Driver 560.81] Windows 10, 6000 mhz

New 560.81 NVIDIA Studio Driver ABSOLUTELY improves AMD 9950X and RTX 4090 performance. I speculate same goes for 7950x3D (as I saw identical behavior of same driver 555.85 working identical on both CPUs)

0.1% turned from 62 fps or even 42 fps 0.1% Low to around 100 FPS to 122 FPS 0.1% with a new driver.
INCREDIBLE STUFF! GPU usage went up anywhere from 15-35 percent in Insurgency Sandstorm.

Do not use Game Ready Driver 560.94 Windows 10, this driver results in drop of 10% in GPU usage in RDR2 consistently from 90% to 80%

Educational moment here is that at the end of the round I get a crash. This is caused by RTX 4090 perceiving card being physically removed with "Device Removed Error" that can be fixed by doing the following RegEdit entries:

I did not do this fix since installing AMD 9950X on fresh install of Windows 10 Pro, as it's been only couple of days of checking the CPU.
On 7950x3D I had this entry added and had no crashes in Windows 10 Pro or Windows 11 Pro

If you own RTX 4090, I highly suggest doing this fix. Many unreal games will crash with identical error and RTX 4080 can crash with similar message, so the fix works not just for AMD or Intel, it works for both companies, but it is specific to NVIDIA cards.

*FUN FACT*: Running lower voltage on VCORE with 9950X resulted in decrease of performance by SIGNIFICANT margins in multi-threading and single threading.
My Cinebench R23 Stock is 40274
While lowered voltage to 1.32v results in score of 30411. Simply because you lowered the voltage.
Curve optimizer actually increases Cinebench score and performance (Negative Offset), but voltage reduction gimps the chip putting it into ECO Mode. I believe changing voltage like that results in hard limit of how much voltage each core can use, and thus results in a hard brick limiter to the frequencies. As I saw as little as 3.3 ghz in Multi-Thread test of Cinebench R23.

Stock + Curve Optimizer is the way to go, but not the voltage itself. Unless your intent is to reduce overall voltage, at increased decrease of hit, but with a HUGE impact, essentially 25% or greater performance decrease, just by changing stock voltage of what was showing around 1.359v or so to 1.32v). Don't change voltage, unless it is your intent to limit heat and performance of the chip. Could be useful for small chassis PCs that are thermally limited by cooler choice, or you are limited electricity for non-gaming situations. I can see some scenarios for that, just not how Intel does things, so it was super interesting.

All my benchmarks prior to today were ran on lower voltage, essentially limiting my chip's performance to a greater sense of a word. Returning to Stock improved gaming and operations of Windows dramatically.
