It's my first post here as I only got into DCS a few weeeks ago so first of all hello everybody.
I've been enjoying DCS a lot but there's something I noticed rather quickly. Especially when flying low, the sensation of speed is just not there.
The most obvious thing is the size of trees. This is definitely a major factor and I found an easy way to check this. I was flying low at about 600 km/h over trees and watching the fps counter. Then I flew above a road with a power line next to it. Despite the fps staying quite consistent, the perception of speed was noticeably different. The reason is that our brain figures out, based on the tree size, that we must be moving slower than we really are because trees that our brain is well used to are just not that big. Get away from the trees and look at the power lines and suddenly you feel you're going faster.
The second factor that I discovered plays a huge part is the monitor refresh rate. Most standard monitors it at 60 hz, which means you'll never see more than 60 fps displayed in-game, even if your GPU is a monster that runs the game at 150 fps. I learned you can "overclock" your monitor with the Nvidia control panel (no idea about AMD). If you're lucky, you might get a refresh rate 15-20 hz on the same monitor which will allow you to see these 15 or 20 more frames when flying. And God does it make a difference. Suddenly everything became smoother, faster and more real. I managed to reach 75 hz on my 60 hz Samsung monitor which I am not really satisfied with in terms of image quality, but at least it reached 75 hz which is already pretty good AFAIK. The catch is though that you need a PC powerful enough to run DCS consistently at 75 fps or whatever your maximum refresh rate now is if you want to take advantage of this.
I now regret not buying a higher refresh rate monitor. Though on the other hand my GTX 1060 wouldn't allow me to benefit from 120 hz or something like that anyway. It also makes VR more appealing to me now as even the Rift has a 90 hz refresh rate. That would also explain why some people flying in VR say their sensation of speed is OK.
Please share your experience with this issue. Who knows, other people might think there's no problem at all! I'd also be interested to know what refresh rate you guys were able to reach on your 60 Hz monitors if you are willing to try the method I mentioned. I'm wondering if the extra 15 Hz I got is good or average at best.
As to the trees, if there a mod out there or an easy way to reduce their size ? Also, do trees on the DLC maps have the same size or are they different ? It might be Caucasus only thoughI remember watching a video on Normandy map and they seemed too tall.
Could someone from ED comment on the possibility to include an option for normal/reduced trees in the settings ? It seems to me they need to be around 40% shorter and also narrower.
