Testing for anti-virus/Windows Defender latency adds?

[Voyager]

Reading through the VR setup guides, and noticed the comment about using only Windows Defender, due to added latency. 

 

I'm wondering, do we have a way to test that in Il-2? I'll have to go digging, but I do recall other times I've seen virus scanners tested, Windows Defender was not actually faster than other virus scanners, so I'm wondering if we can test that directly here?

I personally just add my games to an exception list in Defender.

Have we measured to perform impact of that? From the WD/BD tests, it looks like we could be leaving ~5% free performance on the table.

From what I've seen there's zero activity from WD when a folder is in the exclusion list and it only seems to get slightly active when there's lengthy file operations happening in non-excluded folders. You won't see any benefit for GPU-related functions and even if it did run something in the 1-5% CPU usage range (depending on CPU) its effect on a game like IL2 would be negligible if any - I think the most effect it would have would be when copying large amounts of data and/or OS startup.

 

Also keep in mind that that video is from 3 years ago and is running under a virtual machine so certain operations can have different effect than they would in a non-virtualized environment.

Ok, so actually ran the tests, using Norton 360, Windows Defender, Bit Defender and Kaspersky anitvirus software. I used the SYN_Vander BENCHMARK v6 CPU benchmark test, and did 3 runs of each. My CPU is a 5800X with 32 GB of DDR 3600, and a 1080 TI GPU.

 

I've attached the results in a tab delimited table below, but, they were all within 1% of eachother, and there was no difference between having them turned on, or off.

 

One of the three Bit Defender results was a lot lower than the other two, but I suspect that was an anomaly rather than a trend.

 

Given these results, I'm not sure it makes sense to recommend removal of most top end AV software.

Interesting. I use Kaspersky myself and haven't had any issues with anything on Win10. Not that I use VR but just saying. Microsoft seem to be fond of telling users what apps not to use and steer them toward their own products.

Or else!   They say the same about CCleaner for instance and I've never had any issues with that either.
