new field of view option might be relevant to DCS, as we already have a built in world scale setting the second one probably redundant.

FOV

Does exactly what it says on the tin, reduces the field of view providing additional clarity in terms of performance

So test 39 was really to baseline 5.690 against 5118, there were no significant changes so I continued to use 26 as a baseline, similarly with steam version 1.17.8 itself in test 40.  In test 41 I wanted to bring it back to 100% to see how it performed and give me a sense of the visual acuity improvements.

 

Broadly the FOV does what it say gives you improved clarity at the cost of decreased FOV, 95% is liveable with and produces some  small performance differences... my view on this is you are basically "robbing peter to pay paul", and while there are some marginal performance benefits it doesn't outweigh the "cost" in FOV loss.

 

If you are on lower spec hardware then this is something you should consider carefully though as a 1ms here and there can make a difference. 

 

World Scale

The world view slider is not enabled by default, you have to scroll down to the bottom of the Manage Custom Video settings for DCS, and click on the Override world scale button to ON. 

 

I only ran two tests here I might do more, but probably not, in summary this kind of does what the IPD does in DCS  VR settings, at 200% you look like a GIANT and at 50% you look tiny. The surprising thing for me was they BOTH have a very similar detrimental FT impact on the GPU, its not huge and I haven't really tested IPD in game to see which is going to be the better fit:

 

			Frametime in ms		Delta From Previous
Ver	Test	Baseline	GPU	CPU	GPU	CPU	Changes
2.7.0.5118	26	Test 21	10.70	7.39			Shadows Reduced Frame Rate Impact MOD
2.7.0.5690	39	Test 26	10.72	7.44	-0.03	0.21	5690 baseline 80% CRM
2.7.0.5690	47	Test 26	11.09	7.30	-0.39	0.09	Steam Version 1.17.8 80%CRM 200% World View
2.7.0.5690	48	Test 26	11.12	7.22	-0.43	0.17	Steam Version 1.17.8 80%CRM 50% World View

 

My summary on this is if you feel you are two big or too small play with it and see what works for you there is a small, likely proportional, impact on perf which ever way you flex the slider.  But ultimately knock yourself out ... 

 

I will be leaving both these settings at default.

HTH

Did 200% World view change something with picture clarity ? Did it improve anything?

Doesn't get HTH? What does this mean?
