Patch did absolutely nothing for the stuttering around built-up areas for me, almost felt worse in fact. Back to using the process affinity fix :/
Frankly, even the affinity/priority fix doesn't do that much for me in Surfers.
I don't blame the people who went for a refund, after all it's at least a 50 quid game and it behaves unpredictably for so many gamers on a wide range of configurations.
No way is it worth 50 quid (let alone 80 for the ultimate) if it doesn't work properly but that's something some fanboys in this thread like to sneer at, even on this page.
I'm going to stick with it because I'm having fun but having paid 70 quid for the Ultimate I'd like to know I don't have to disable my av, mics, then click on the icon fifteen times to make it launch, set task priority to low, change CPU affinity and still put up with stutter/drops in certain areas on a PC that's far from a potato. There are some minor graphical glitches as well.
It''s a bit too much for such a big, expensive release. No other game I've ever owned required doing such stuff.
