Do we still have to use GeForce 332.21 driver?

One updated GeForce driver after another passes by but I still stick to V 332.21.
Will there be any official announcement when it is ok to switch to the actual (337.88)?
I tried the one before and my PS2 wasn't playable anymore... So I went back to 332.21. - but I don't like the idea of sticking to old drivers.

337.88 is working fine for me.

337.88 is fine here as well OP

Like you I stayed on v332.21 untill a few days ago when I installed v337.88 for my Star Citizen Arena Commander, I half expected problems with PS2 but up untill I last played on live a few hours ago everything looks great.
I'm playing with a GTX 590 and SLI switched off (have to do this when playing Star Citizen)

Nvidia already fixed the freeze in the last WHQL driver

The drivers were never the problem. My ancient 314.22 drivers black screened after one of the updates.

latest drivers are fine, no lockups/freeze.
