I've now tested on RHEL 5, 6 and 7 with both GNOME and KDE (Plasma), 
with glxgears and have seen no issues.

 From my understanding, nvidia first enabled GLNVD in the 361 beta 
release and there were some reported compatibility issues, mostly with 
games I believe. In the 361.28 driver release they then incorporated a 
legacy libGL library and made that the default.

The 364 driver release then reverted to making GLNVD the default again, 
hopefully after fixing some of the issues and the 367 beta release 
brought in some ABI changes.

So hopefully the current 367 release should be more stable no most of 
the issues have been resolved, so the next major long lived release from 
nvidia may be a sensible time for elrepo to roll out GLNVD enabled 
packages by default.

In fairness to nvidia, a lot of the incompatibilities with some games 
was due to hooking in to unsupported non-standard features of the old 
driver which are no longer available in the GLNVD enabled driver ABI, so 
these are issues that need to be resolved by the games vendors. If this 
is limited largely to games then it is not something that need overly 
concern us an Enterprise Linux users, but I would like to receive as 
many reports as possible from Enterprise users using a wide variety of 
applications.

So at the moment I see no reason not to consider rolling out GLNVD 
enabled packages.
