Performance drop when looking through glass

Elpin

Is it just me or did also anybody else noticed a large FPS drop when looking into shops through glass?

I stand in front of the shop selling suits and when I'm at the entrance and looking in, I'm getting 30 FPS. And then all I need to do is strafe left to get in front of the window next to the entrance and the FPS suddenly drops to 14 FPS. How come?? I look the same direction forward into the shop, I see the same things... the only difference is the glass in the way. And It actually doesn't stay there. Anytime I see a glass in the scene, like on the walkways and such, the FPS drops.

Actually, speaking of FPS... they really seem low. I have a GTX 1070 and I usually don't have an issue with any new game to keep it running around 60 FPS on high settings and 1440p. Here I turned it all down to low and I still get only 20-30 FPS inside starbases (depends on which direction I look). I mean... the latest RTX 3070 is roughly 2 times as fast as 1070, but I definitely wouldn't expect to play at around 40 FPS with a 800 dollar card!

It's called optimisations, there wasn't any in the Alpha, and this Beta there are apparently some, but most people seem get the same performance as Alpha.
I only have a 1060, I turned off vsync and frame limits in Horizons and get 140+ FPS looking a guardian pillar - same pillar in Odyssey I get 40 FPS.

my rtx 3070 can go from 110 in a station to 25 fps if i look in the opposite direction. relog and all is fine again. Maybe a memory leak??

Interesting. I had actually expected this and even assumed that it would not be possible to look out of a window to observe the current air traffic for precisely this reason. To my great surprise, this did not prove to be true. I also can't notice any FPS drops when looking through glass, which is also something I incorrectly predicted. I'm running a GTX 3070 and have no idea why it's so different from a GTX 1070 in this regard (that the performance is generally higher is of course beyond question).

I'm curious if there are others who can confirm this effect with weaker GPUs. One possible explanation could be that the RTX GPUs come with an enhanced instruction set that can better handle views through glass in general and reflections in particular.

my rtx 3070 sometimes suffer in a station concourse, with fps even as low as 25fps, and a relog bring the fps up to 80-110 again.

Playing tinkering with gfx settings can break performance semi-permanently.
Rolling back changes that caused performance drop does not help - sometimes game just got "stuck" in lower fps after I tried setting something too high (e.g. supersampling) even after I turned it back off i could not get my 60 fps I had before this change - only restarting game helped.

This behavior is tricking many players to false conclusions what the actual performance is - because they keep lowering the settings with no results they assume game runs in low fps even on low settings.

What is only partially true, after I manage to find my "perfect" settings that were maximizing GPU usage but not exceeding it (in my case goal was 60 fps even in "worst" scenario - concourse and settlements) it runs stable like I wanted, unless I start to play with settings too much again.

Here is a "proof" video: 60fps in concourse at 2560x1080 on GTX 2070s with most settings on ultra.

I see this sometimes, but rarely, and only for a second. It's probably worth looking at specific settings to avoid comparing apples to oranges. I run everything in Ultra wherever possible, the rest in High, but with a super-sampling of only a modest 1.0. With those settings, I rarely see my FPS drop below 70 in station concourse. If I increase the super-sampling to 1.5, my overall performance drops by about 1/3, which is to be expected and natural, I guess.

The GPU is at 100% the cpu barely used. All ultra and the SS at 1x.

I know that, I don't play with graphics option after erase the graphics folder and setting all in ultra afterwards. The problems appear randomly and the fps fall to the ground. Normally I get 80-110 in the concourses, but sometimes....the fps drop to 25 without reason.

Let me visualize you something with pictures. I was using a NV inside a PWR building and I've noticed that glass inside the building reflects what is outside through solid walls.

Internal glass in the building:

The view of the reflected side:

One of the corridors. The glass that reflects the star is on the left:
