Low FPS when in-game, but not while spectating?

[Rapidgame7]

I haven't played for quite a while so I can't be sure when it may have started.
When I'm spectating, FPS vary from 60 in some maps to 200 on an empty editing map, but whenever I am in game (no matter if in first person or third person) or I am following somebody without the TV spectator, FPS lower to 30 FPS.
I recall that not happening before.
I've been messing around with the graphics and some interface toggles but even on the lowest settings possible the game still runs slow.

Am I doing something wrong?

Since 1.5.x, elements in the HUD had been giving framedrops to some people (me included), which is why when you are in free camera mode, you don't get the performance drops.

Try going into the console and type this: /inventoryinput 0

It may solve your problem.

Sorry for the late response.
Yes, disabling the input display fixed the FPS problem. Thanks!

A few minutes ago I went to a race map and I saw the input display enabled. Setting inventoryinput to 3 (I wanted to test something) and changing maps happen to let the display appear with no changes in FPS.
Is that normal?

During my work on the new UI, I found a memory leak in the system I made for converting keybind lookups to pretty images of keys. I back-ported the fix to stable, so if you've auto-updated then this shouldn't be an issue anymore.
