Since the last update, all my aircraft steer to the laft while taxing and have to constantly correct and over correct.

Sounds like prop torque which you need to correct with right rudder.  Maybe you were using auto rudder and it got disabled by the update.  Possibly your realism settings have somehow been changed.   

I was forced to change all my graphics settings after installing SU13 and I don't know what other settings might have changed.

I have had this problem for some time.  I use the TCA sidekick and not sure what calibration setting I need so it stays straight...lol.

Also - if you are using pedals, double check you do not have a brake pedal partially stuck on.  

Yeah, it  happens for me with all planes, all take offs for me too, for several weeks now (I was in the beta and I think that is when this issue started).

As you know, the MSFS Sensitivity settings display has something called Neutral. This will put a bias left or right on the rudder when rudder pedals are in neutral. I have been using 33 or so for Neutral on the rudder axis. I imagine other makes and models of pedals need another number (I use Pendular TM pedals).

This keeps all planes flying in the air straight ahead when no rudder input is pressed. The planes will still slightly try to go left on take off runs, but this is just normal engine torque. Before I reset the Neutral slider, all planes would veer very sharply to the left on take off runs. (I think this started with the sim update beta release).

Forever, I used to fly with Neutral setting at 0. Starting a few weeks ago, I have to use 33 or so. This makes the plane perfect in the air and on the runway under power too. It's not a compromise, it makes rudder neutral perfect. On small planes which have no rudder trim, it takes maybe 40 seconds for compass to drift 1 degree. That's as perfect a rudder trim as I ever got since the sim was released. 

As stated, for real aircraft you have to add a bit of right rudder for taxi for takeoff.  Maybe that's what you are experiencing.

P-Factor and torque are not a factor at taxi power settings. They are only a factor at high RPM and low speed such as during takeoff and climb out. At low taxi rpm no right rudder is required in a tricycle geared aircraft. 

Left or right - IRL small GA airplane never taxi straight. Surface imperfections, wind, tires and etc all play role in front wheel swinging left or right. First lesson we teach is use rudder and throttle (not yoke) Small adjustment pretty much required all the time. We also hummer not to use brake when not necessary. First throttle to idle then brake.

 It's not uncomment for a beginner student pilot to struggle keep centerline while actively swinging yoke (car habits) LOL We do use yoke during taxi but only during srtong winds or uneven surface .  Most light GA planes (Cessna, Piper and etc) rudder attached to front wheel allowing creating degrees of steering - so rudder  is our taxi friend!

I am finding out that this is now the case with me too with MSFS Steam.

I've not changed ANYTHING but now after the current update to MSFS the rudder is extremely sensitive. The rudder on the default TBM 930 now reacts to pressure on my very simple non-force feedback joystick (Logitech Extreme 3D). My Just Flight PA-28 also now veers to the left, so much so that I am unable to take-off. And I don't have anything in my Community folder either.

I checked the joystick including using it in P3D's version of Just Flight's PA-28. The joystick works perfectly. Since there's nothing wrong with the joystick, I've concluded the issue is with the last MSFS update.

You may want to try flying straight and level with no winds. Just to see if this new behavior is only happening on the ground. I had a bad leftward drift every altitude. It started about the same time as the SU beta. Changing neutral in controller settings cured it. I can't be sure what caused it.
