Laggy Animations in Finder / Lag in Games

According to Samsung's site, TRIM is supported, but so is an automatic garbage collection algorithm. Apparently Apple's TRIM conflicts with this, and causes worse performance. TRIM is currently disabled. I have a m.2 version of the 850 Evo (500GB as well) in my Macbook Air, and it runs fine, and has been in use longer then this one. (The one in my Mac Pro has been in there for only a couple months). Disk read/write times appear to be close to what they should be.

I've noticed the lag is more noticeable when moving maximized windows, or large windows. Perhaps OS X doesn't work well with larger resolutions? This doesn't make much sense though, as the retina Macbooks/iMacs are running OS X fine at much larger resolutions, and on lower end hardware.

I have now enabled TRIM with the TRIMforce command. It didn't seem to fix the lag, but I suppose it'll be good to have.

I have removed the PC Quadro, thinking that maybe it was conflicting with the Mac one due to their different ROMs, but it hasn't made much of a difference (Both were connected to one monitor each).

I booted into safe mode, oddly enough, I noticed that besides the screen tearing (Which I think is caused by a lack of a graphics driver, though both Quadros were still reported correctly) everything ran a lot smoother in safe mode. Moving windows was a lot more fluid, acting a lot more like it does on my Macbook.

Perhaps something else I am running is causing the lag? I always have Flux and Hyperdock running in the background, but removing them doesn't seem to fix the lag. Opening activity monitor shows that only 0.14% of the CPU is being used, only 6.44GB of RAM is being used and there are no reads and only one write per second.

I'm not sure what could be slowing the window manager down, but it doesn't appear to affect it in safe mode.

I am not running any virus scanners.

If I get some time this weekend, I'm going to try and add/remove hardware, as well as try a few uninstallations/installations to attempt to narrow the possible issues down.

I found this article on OSXDaily that seems to have sped the resizing animation up substantially. It's still not quite as quick and smooth as my Macbook, but it's much better then before.

I've swapped the GPUs for some others I have lying around, a Geforce GTS 450 and Quadro FX580, but neither seem to change the amount of lag experienced.

Is it possible that my CPUs could be the problem? There is a 25 second or so delay before the boot screen appears, and I had a similar problem when using them in another PC (A Dell Precision T5500 with a similarly lengthy delay before the BIOS splash screen). I didn't think much of it, as that seems to be their only issue, but perhaps OS X does something with the CPU that uses the same bit of the CPU causing the hold up when booting.

They are a matched pair of X5675 Xeons.

The extensions appear to be the same on both the Macbook and Mac Pro. However, I did do a file transfer from the Mac Pro to Macbook when I first set it up, so I assume some of those got copied over.

Is there any way to see which ones are actively being used?

I decided to delete a few kexts that didn't seem like they were being used (Caldigit Raid, Highpoint AHCI) and noticed Finder windows now resize smoothly, and move between monitors without lag. Tried a few other applications and they resize smoothly too.

Firefox is one of the few that doesn't, but it has the same problem on the Macbook, so I assume that is due to some issue in Firefox and not OS X.

Lag in certain games was not fixed, but that is probably another issue specific to the individual games, as I tried a few other games, (equally demanding as TF2 and Cities) and they ran fine.

VMware seems to only lag a lot when running on my secondary monitor (Running off the PC Quadro) now.

It still lags a bit on the primary monitor, but not as much as before.

I will mark this question as answered for now, and go ask about the remaining issues on the forums associated with those applications, as the OS X trouble seems to have been fixed.

Unfortunately, my monitors only support their full resolutions over Displayport (Or newer HDMI standards, though I haven't gotten it to work using DVI adapters) and the OEM Mac Quadro only has one Displayport output. I also use the DVI on it occasionally for a projector (Using a DVI to HDMI adapter) and an Oculus Rift DK1, and that pushes it to the Fermi limit of two video outputs.

If Apple were to add daisy chaining support to OS X, I could probably use one output, but I'm not sure the 4000s even support Displayport daisy chaining.
