Be sure the "Low Latency Mode" within the Nvidia Control Panel, beneath "Manage 3D Settings" is set to "on".
Setting this to "Ultra" can cause stuttering.
Setting this to "Ultra" can cause stuttering.
I don't know if this is of any significance or if it helps narrowing it down, but I noticed that alt-tabbing out of 3d application will produce this stutter again with RTSS even if it is 3, 4, or 5th time of opening it.Well then, if you're sure it's not ESET then it's back to my original draft.
You've got this issue with drive access. It's either the spec's just not up to it, there's a hardware problem, or there's a software problem.
They're old games on SSD so if the spec is fine it looks like a hardware or software problem.
The CrystalDiskMark scores look spot-on across the board, temps and health are fine, so it looks like it must be a software problem.
If it's across all games, it's something more fundamental than an issue with that one game.
If you're saying that the obvious ones like drivers and settings can be discounted, and it's not any of the other processes you've got running, then there's not a lot left to try. Reinstalling Windows is about all you've got left, but if you don't want to do it without a guarantee that it's going to fix your issue then you're stuck because I can't see how anybody can genuinely give you that.
I will say on this bit:
So maybe you have indeed disabled some important process or service and a fresh Windows install is necessary. To be honest, the days of keeping the system tray to a minimum for 'maximum performance' are long gone now that multicore processors and OSs that can use them are standard. I haven't bothered doing it since WinXP. You're running an 8-thread processor with 16 GB RAM. Unless you absolutely know that a background process is causing you problems you're better off just ignoring it, rather than deleting it because you're not sure you need it. Chesterton's Fence.
I tried LatencyMon, does this help with anything?Well then, if you're sure it's not ESET then it's back to my original draft.

So ATAPI Driver Extension has the highest DPC and execution time outside of the monitor. On a system that doesn't even have any legacy drives I can't see why it would even be running. I can find ataport.sys in my System32/drivers/ but no evidence of it running at all, although this is Win 11.I tried LatencyMon, does this help with anything?

I unplugged both P300 HDD's but no difference.So ATAPI Driver Extension has the highest DPC and execution time outside of the monitor. On a system that doesn't even have any legacy drives I can't see why it would even be running. I can find ataport.sys in my System32/drivers/ but no evidence of it running at all, although this is Win 11.
Given that it's a disk-related process that's spending a lot of time interrupting when it probably shouldn't even be running, and you're having problems when accessing the disk, it seems like a decent clue.
It might have been that during your process cull you did something that caused Windows to fall back to ataport.sys or otherwise gave it undue prominence, again pointing to starting over with a complete fresh full reinstall to see if that fixes things.
I'd be minded to try running the games with those two non-SSD drives physically disconnected, to be absolutely sure the system isn't trying to access those during the games for some reason.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:12:00 (h:mm:ss) on processors 0,1,2 and 3.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 13427,195356
Average measured interrupt to process latency (µs): 9,346154
Highest measured interrupt to DPC latency (µs): 318,336548

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: ekrn.exe
Total number of hard pagefaults 19771
Hard pagefault count of hardest hit process: 7506
Number of processes hit: 12

Interestingly enough when I went to driver support page https://www.msi.com/Motherboard/H97-PC-Mate/support#driver and selected Win 7 64 I can't find Intel RST, but once you switch to Win 10 64 it adds a new tab called On-Board SATA AHCI/RAID Drivers and that driver is right there.You uninstalled the Intel SATA driver because you thought you didn't need it, you seem to have lots of interrupts from an old MS driver that's mainly designed for IDE optical drives and you appear to be suffering from stuttering every time your games access the hard drives.
Just bite the bullet and do a full fresh install, install all correct drivers, don't remove anything and take it from there.
