There was been a lot of talk about lag in the 950 thread so I thought I'd buy a Leo Bodner tester and see for myself as I currently have both sets.
TLDR;
Both sets average low 50ms. PC mode/GAME doesn't seem to change matters, although ISF mode seemed to have least lag strangely. Clear motion takes lag up to about 128ms. Setting sound out to headphone rather than speaker didn't seem to make any difference.
I turned all processing off for both sets, and tested with the input type as PC, HDMI and HDMI that was labelled as PC (as some people thought that made a difference on 930). In each of these I tested GAME and ISF 1.
The Bodner device displayed different measurements each go, and could vary over 10ms with each run. For example, one reading for the top bar might give 43, then the next time I might see 60! I've taken 4 reading for each bar on each setting for the 920, 5 for the 950, and averaged the results (which is the last one in the row). The data below show top, medium, bottom bar data in that order.
What is the takeaway? PC/GAME mode doesn't seem to alter the reading the Leo Bodner device gets. Owners can game in ISF modes with no added lag, and possibly slightly less.
Personally I used my PS4 on Console input and used True Motion when playing Soma and I didn't feel any lag. I actually preferred strafing with True Motion on.
When I ran my PC through the 920 and 950 using a steam controller I could not feel any lag when moving the mouse. Some people have said mouse movement was 'swimmy'. I did not see this at all. However, it should be noted that the inputs were direct to the tv. No doubt there would be lag added if the signal goes through an AV receiver.
To me, the 920 and 950 felt the same when playing MGS V. I haven't tried much on the 950 yet, but Geometry Wars, and old school 2d shoot, felt perfectly playable on the 920.

No sound – highest was 69, lowest was 47, so seemed about the same
