Here's my 2 cents with golden tee pc and tiger woods 2005...
I'm running both on the cab, and initially can into the golden tee pc can't hit a hooked shot.... Reset back to normal mouse sensitivity and run through the swing calibration a few times, if you crush the ball during the calibration, it tends to make the sensitivity a low lower. nice normal followthroughs during calibration make the "english" a lot more responsive. Also look for the pc version of the swing guide (mousepad) , I think I last found it on the golden tee PC website, the hooks and slices are opposite if I remember correctly from the arcade machine.
I also ran into the "can't hit over 80%" in TW2005. Are you perhaps playing as one of the default players, such as tiger woods? I noticed that tiger never hits over about 80% no matter what you try, but a player you create can hit the 100% and overdrive shots. But also Tiger woods uses trueswing (tm) technology, which, unlike golden tee which is about pulling back and killing the ball for power, TW requires a smooth and rythmic swing for best results and power.
We usually end up playing weekend golf tournys on the cab now, Tiger woods 2005 is the preference by far, as we've made custom characters using the character customizations (isn't is called trueface?) that look like each of us.....
Now if I can only figure out how to stick a beer bottle in hand and a smoke in mouth, the illusion would be complete.....

(p.s. NEVER I repeat NEVER create a character that looks like your pregnant wife..... 6 months and she still brings it up every weekend)
