DX11 vS DX12 comparison (stutters, Framerate dips)

maxresdefault 1024x576 - DX11 vS DX12 comparison (stutters, Framerate dips)


Test system:

GPU – NVIDIA Asus RoG 1080Ti

CPU – i7 7700k (not overclocked)

RAM – 16gb Corsair 3000Mhz

OS – Windows 10

(Also, I have my game set in the launcher to use 4 worker threads)

All in-game settings were set to Extreme.

Resolution is 2560×1440

FOV is at 100.

Now I don't know why this is, but I was troubleshooting my own framerate loss and frequent stuttering in-game when I noticed that, when playing with DX12 enabled (which I've had on since launch) my GPU usage was actually 0%. Which is definitely super weird.

When I switched my settings in the launcher to DX11, suddenly my GPU usage jumped to 100% while my CPU usage stayed about the same-ish (minus about 10%)

This has improved my framerates considerably and seemingly eliminated stuttering (that I can tell, so far, for me, specifically, citation needed)


When running with DX12 I was averaging about 85-90 FPS in a normal map region, dropping into the 60's and 70's during hordes and frequently stuttering.

When running DX11 I was regularly upper 90's and even as high as 125 FPS during calmer parts of the missions, never dropped below 90, and so far, after TEN test games on various maps, have not stuttered a single time.

I realize this experience is anecdotal and questionable at best, and may even be specific to my rig, but I thought I would at least post this out here to hopefully help at least a couple people possibly fix their framerate and stutter issues.


P.S. It's worth mentioning for anyone who might be wondering that switching from DX12 to 11 has absolutely no effect (that I'm aware of) on in-game visuals. Everything looked exactly the same for me.
