Encryption in general can impact performance, but I'm not privy to how much because I don't use it. Personally, I don't recommend BitLocker as it's closed source.

Encryption can be done by hardware (accleration) but generally there will be performance overhead that you otherwise wont have.

 

Personally I would not even consider that on my gaming rig, every ms of frametime counts for me. Rather i would get a small notebook and choose an open source solution and just do, whatever i want to hide, there. Imo it is just not worth to pollute my gaming rig with more processes and overhead. I use an T495 with Ubuntu Eoan and LUKS.

what is opensource you mean tho?

Sry i am not a native but if you are asking what Open Source is then i have it linked right there for you. Tldr it is software that comes with or does publish its source code in a manner that anyone can publicly access and even contribute (fix bugs, refactor logic, etc) to the source code - most of the time it is also licensed as "free".

Nope, no impact. Tested it before enabling it on my drives, I get the expected performance on all of them. It's all done in hardware.

If your chip has an hardware acclerator built in for that then its going to work like that, espicially pre-bitlocker era devices do not have that.

Yeah, but that means a >10 year old machine.

My 2011 Machine had none, but there are also external TPM Modules for JTPM headers (Wish i knew that earlier ). Still, encrypted data has to flow to the tpm and back, that overhead imo.

[Kilrah]

That's not how it works, the actual data doesn't go through the TPM, just key exchanges. 

There certainly will be a bit of overhead somewhere, but not anything meaningful. I can still get my 3.3GB/s reads and 2.2GB/s writes on my NVMe drive with bitlocker.

I doubt it would impact gaming performance.

 

I would expect most of the encryption takes place when writing files to the hard drive. I don't think this happens a lot when gaming, except for writing save files. You might experience slightly longer load times due to unencrypting files.. but I doubt you notice any real world difference.

 

I would enable encryption, open source or not. When your house gets broken into and your PC stolen, you will be glad it is encrypted (I know I was, when my laptops got stolen)

[Kilrah]

I also started encrypting my drives after my apartment was broken into. I'm not using a TPM but a USB drive as key so my PCs won't be accessible in any way without it (or the recovery key obviously) and I keep it with me.
