I posted this in a new thread, but I guess I should have just put it here.
Bug #1: anisotropic filtering drops to 2x whenever a new maps loads
Anisotropic Filtering (AF) is controlled by the cvar vt_maxaniso. The default value is 2. If you set it higher than that and load a game, it will render using that value. However, as soon as you load a new map, it will render with 2x AF. vt_maxaniso will still be set to a higher value, but it doesn't matter.
On a side note, the new patch sets the maxiumum value of vt_maxaniso to 4. This is to prevent texture seam artifacts from popping up. These seams are only visible if you smash your face into them, though. You would never see them while driving.
The fix: fix the bug in the engine that keeps dropping to 2x AF
Even better: automatically increase AF to 8x while driving
Bug #2: janky mouse cursor control
When you're aiming a gun, the mouse input in this game is great. As soon as a cursor appears, though, you have to struggle with an over-responsive cursor that doesn't want to go where you put it. The problem is caused by input post-processing. You have to deal with everything that typically gets applied to the right anolog stick of a gamepad - a dead zone, acceleration, smoothing, and angle snapping.
There is a variable, m_menu_sensitivity, that used to help, until the new patch locked the cvar. Even when it worked, it only applied to the inventory screen, not vendor menus or anything else.
The fix: Enable unfiltered mouse input, only accelerate the cursor if the user has cursor acceleration enabled on the desktop
Even better: enable m_menu_sensitivity, make it work everywhere
Bug 3: Missing interface elements
While playing this game with a gamepad, you will be able to navigate any on-screen menu or prompt by pressing buttons. For example, you can press the A button to clear a message. When playing with a KBAM (keyboard and mouse) you can only move the janky mouse cursor over to a clickable button. There is no reason why you shouldn't be able to press the default 'Use' key to clear that message.
There is another issue in the inventory. When looking at your items, you can double-click on certain deployable tools to use them immediately, which is nice. The same functionality is missing in the list of weapons. I'm certainly not going to find any convenience in the quick weapon selection (small sets of clickable icons at opposite ends of the screen? really?)
The fix: tweak the interface for more ease of use with a KBAM
Even better: don't force your developers to playtest with gamepads
