I have it on an older GTX 770 with 2 Gb VRAM, it doesn't happen on my current 1070 GTX with 8 Gb. Looks to me like a resource leak, check your free VRAM with nvidia-smi right after game launch and after the round. Mine is almost fully occupied (1900 out of 2048 or so), the driver is probably spilling the resources to the regular RAM which is much slower hence the slowdown. Try to change the quality settings inside the game to medium or even low meanwhile, it should help.
I can confirm what rkfg said:
memory.total [MiB], memory.free [MiB], memory.used [MiB]
Before game:
1997 MiB, 1414 MiB, 583 MiB

1997 MiB, 233 MiB, 1764 MiB
1997 MiB, 233 MiB, 1764 MiB
After round:
1997 MiB, 80 MiB, 1917 MiB
1997 MiB, 80 MiB, 1917 MiB
1997 MiB, 83 MiB, 1914 MiB

1997 MiB, 83 MiB, 1914 MiB
1997 MiB, 83 MiB, 1914 MiB
It looks like its using a lot of VRAM during the match with only ~250MiB left, but that's enough for the game to run smooth. Once the match ends, there seems to be an increase, and the whole system gets super slow.
Set the textures to medium, on my GTX 770 with 2 Gb of VRAM that's the only thing I set to medium, everything else is on high, and the game runs good for more than one round.
I have exactly the same problem on my 1050 Ti 2GB. Everything runs great maxed out ~80+ fps, then after every match I have to restart the game because frames per second drop to 30 or even below 30.

EDIT: I tried playing the game on medium settings and the issue disappeared. I take it as a temporary workaround, still hope it will be fixed one day.
Same problem here with Ubuntu 16.04, GTX 960 (driver 415.18). The problem is especially apparent when playing the "call to arms" event. In the first match I get stable capped 120 FPS and in the second match I only have 20 FPS.
Same problem. Problem also very notable when playing the card "Routed" which gets a terrible slow animation. System information:

Your system information
Please describe your issue in as much detail as possible:
First of all sorry if this is the wrong place, but I didn't find any Artifact specific issue tracker.
When playing Artifact I get a reasonable 60-80 FPS while in the main menu or during the first match after game launch. However, once I finish the match, the FPS tanks to 8-10 and the game becomes unplayable until restart, when everything goes back to normal. This can be triggered even by selecting a bot match and immediately conceding.
During this state, if I manage to alt-tab to the desktop and bring up a task manager, it shows that artifact is using about 10% of the cpu.
Tried to update nvidia graphic drivers from 396 to 415 but that didn't help.
