Need for speed

[etienne1968]

Hi ED développeurs,

I have no words to express my enthusiasm flying your military PC-based sim showcasing such a high realism :thumbup:. I have only one disappointment if I may say so : the feeling of speed at low altitude. Over the years I was expecting that critical immersion factor to be improved from the CPU and GPU technology fast growing.

Unfortunately, it looks like this specific rendition of the simulated flight is impossible to reproduce faithfully.

I fly liners (Airbus 320) and when I look outside flying DCS at 500Kts/3000FT, If have the feeling of 250Kts in real life.

The sim would gain a lot with a better rendition of this criteria.

It’s just a personal opinion from a sim enthusiast following up your products from SU-27 Flanker.

Keep up the good job and happy new year

Regards :pilotfly:

It's a 2D screen etienne1968, try zooming your view back Number pad / and * to have more "peripheral vision" like in real life.

 

Hard to see gauges in a cockpit on a flat screen zoomed back like that, the speed feels more correct tho.

 

In VR it looks much much more accurate and fixes all that. Try it if you can...

David OC, what do you mean?

In VR, the sense of speed is different ( better ) ??

@etienne

As you do not choose to list your pc specs in your signature , this post may be irrelevant...

 

I lately upgraded my GPU from a 1060 3gb , to a 1070 . In both cases i ran with vsync on , and was immediately struck by the increased sensation of flight with the 1070 . This puzzled me at first , until i learned of the effects of frame latency , as opposed to fps . Both gpus were locked at (and maintained) 60 fps , but the sensation of flight was so much improved with the 1070 that my pulse would increase when looking to the side low over the Caucasus at 450 knots .

Graphics settings were essentially the same with both cards , as I used the additional power of the 1070 largely for anti-aliasing (1.5 SSAA and 2xMSAA) , which (almost) eliminates shimmering .

Yes better, you are there "in the 3D world" (all around you, every where you look etc.)

 

From your point of view, it feels like your sitting in a real cockpit. Blows you away the first, many times you try it.

 

I still use my monitor as the resolution for online combat is not quite there yet.

Try flying the Viggen at tree-top level through the Caucasus! :thumbup:

 

 

[felthat]

change fov or try vr

 

@Zius this guy gets it :o

The sense of speed is generally a combination of two factors:

 

1- Field of view, the wider the more sense of speed.

2- Object density and scale

 

You can adjust item 1 and item 2 is dependent on the map location. There is nothing really to fix.

[etienne1968]

Thanks folks for your comments,

As Wags said properly there is nothing to fix. My rig specs are high (ASUS ROG GX800VH VR ready with SLI GTX 1080, 64GB SDRAM, 1,5TB SSD,..). I fly mainly in VR (Oculus CV1).. Super Sampling 1,8 from Oculus Tray Tool. At this time I fly solo with an AI wingman in Persian Gulf and Caucasus map. I’m really amazed by the realism and the overall sense of flight in DCS world. But sorry for my persistance to say that the sense of speed at 500KTs/1000FT AGL is matching what I see in real life at a ground speed of 250Kts/1000FT AGL, overheading my destination airport in visual approach...

Immersion in VR is moreover fantastic except when it comes to the landscape passing by at low altitude and high speed.

To be fair enough DCS world landscape rendition is way much better than most of the pro sims I’ve tried so far (Dassault Mirage 2000 and Rafale). The point is that sense of speed is playing a great part of the immersion. All of my fellow French fighters experiencing VR flight with DCS world agree with my subjective opinion. We are very close to the perfection anyhow. I could add that the sense of speed is better in 2D with the cockpit view zoomed out than in VR.

Frustration is coming most of the time when we have the feeling that only a tiny detail is missing to reach out the perfection.

It still comes back to the Field of view and monocular view which you don't have with the Oculus CV1 at 110-degree's.

 

Hardware to mimic real life problem, not a mathematical simulation speed problem.

Thanks David OC for your detailed return. Relevant information.

So I just learned that bunnies apparently have a 189.5 degree FOV per eye, with 19 degree of "overlapping" binocular vision split between forward and backward (and upward as well if we three dimensionalize this concept).

 

 

 

...I'm having a really hard time imagining what that would be like...

 

 

 

Thank you David OC...I think.

Completely agree with etienne1968, DCS, like all 3D simulators, is too slow compared to the reality. Even changing the focal length or any adjustment the speed is poorly rendered.

Yet using the keys "control + w" the game can be accelerated in proportions that exceed the reality.

Only it is the entirety of the game that is accelerated, so interfaces like joysticks quickly become unusable.

The ideal would be to be able to accelerate the movement of objects without affecting the controls of the joystick.

But it is still a wish that will remain unsaid, a pity.

DCS like all other true sims, is 1:1 to reality. 400kts is 400kts, 130kts is 130kts. 1 fight hour is 1 flight hour. 1 flight second is 1 flight second.

 

 

 

Increasing the field of view does not accelerate the simulation nor your plane, neither interferes with joysticks inputs and outputs.

I have thought this at times, but it should be simple to verify by timing travel from A to B over a known distance at a known speed?:thumbup:
