In my live-music (mobile) PC rigs, I use the simplest GPU's I can find. I don't need any kind of GPU power at all, and weight / heat are serious issues. So, all three rigs currently use the MSI NX8600GTS. It does the job just fine.
Recently I've been trying to get my HW buffer lower, in part but bringing down the DPC latency. My average latency is crazy-low, at about 9 us, but I get large spikes form the NVIDIA Windows Kernel ode Driver.
I have read that some versions of this driver are known to cause DPC latency problems, so naturally I'd like to try changing or removing it, hence this post:
-------------------------------------
1: Do I even NEED this driver? Is it a generic driver, installed with Windows10, or is this the driver actually used by my MSI card? My device manager shows "NVIDIA 8400GS" and nothing that specifically says "MSI."
However, there is an "unknown device" listed, and I can't account for it, unless it's that MSI gpu. Could this be the MSI driver, even though it's not listed under "display Adapters?"
-------------------------------------
2: If this is the correct driver, then how would I "upgrade" it? I went to the NVIDIA site, but did not even see MSI listed. I DO see various "Geforce" listings, so I clicked on "Geforce 8 series" and then "GeForce 8400." This took me to Win10 version 342 (slightly newer than what I have now.)
Is this the correct driver?
-------------------------------------
3: Suppose I install the v. 342 driver, above, and my DPC spikes get WORSE. Hw can I get my CURRENT driver back?
-THX.
