Performance with GTX 1650 and Ryzen 5 3600

Quote from Frank III

Well, I decided to make some quick benchmarking with my setup. In the screenshots you can see GPU and CPU temperature, usage and clock speed; RAM memory used; and finally instant, minimum, average, maximum, 1% low and 0,1% low FPS.

CPU: AMD Ryzen 5 3600 / 3600 MHz base, 4200 MHz max boost / 6 core, 12 thread.

GPU: ASUS Nvidia GTX 1650 / 4 GB GDDR5 / OC Edition

RAM: 32 GB DDR4

Logic board: GIGABYTE B450M DS3H / this capped the clock speed of the RAM.

PSU: Be Quiet! 600W

The settings at both games were everything in Ultra (preset "Don't" in LOTUS with terrain detail at ultra too).

In LOTUS I used the following maps: Diorama and Sonnenburg. The vehicle is the default Berliner GT6N.

In Diorama the performance was good: 46 FPS average. Remember that stuttering I commented in another thread? Well I updated the nvidia driver and I adjusted again the settings according to this Lexikon article: NVIDIA graphics card optimization for LOTUS adapting some options to set high performance instead of quality, and things improved... but this is a small map, what about a bigger one?

Sonnenburg, by the way lovely map! 12 FPS average. The stop is Schmiedehof, next to Hauptbahnhof. As you can see the shadows of the tram are failing too and also objects load very late, for example, arriving to a stop the stopping lines of the signs are gone and signals like open all doors. KI cars look like they have seizures.

As this game uses OpenGL it makes me think that this is the main culprit of that poor performance. Will the program use DirectX in later patches? Or Vulkan? I expect that performance will have to improve a lot to reach averages of 60 FPS in ultra settings.

I have a game that uses DirectX 11 to just make a little comparison (a little unfair I have to admit but anyways, just to have an idea of what we can get), I selected places that are very demanding, some in multiplayer. It's Tower Unite, and everything is in ultra settings. If you take the average of all the screenshots and calculate the average you get like 70 FPS.

By the way, I have to say that using the steam workshop is lovely to get new content instead of using the old method of downloading compressed files and unpacking in the game folder like in OMSI. Also Steam checks dependencies so that's fantastic. Everything is concentrated in one only place.

And last but not least I've noticed that some AI cars have some parts of the inside empty, because you can see the centre of the inner side of the wheels without anything supporting them, especially with some Fords and Kias.

As Janine said, just waiting for the next patches to come!

If anyone has the same setup or something like mine, tell me your experiences.

Transfering the game to Vulkan was promised when the game was released for public nearly 2 years ago, but we don't know anything specific about it.

Can be = Promised?

e.g. = exactly?

At least inter-OS compatibility.

Quote from Frank III

It's interesting to port this to Linux, mainly to see how it behaves in a very lightweight system installation.

To be fair, I got the complete opposite of a lightweight Linux, but LOTUS runs very smooth on a Kubuntu 18.04 LTS.

Quote from Frank III

You run it with Wine?

Kinda like. Valve made an investment into Wine to get more and more games running on Linux. So the keyword is named Proton, which is based on Wine.

Sorry, I completely missed this video, which has some interesting points in it.

First of all I want to point out, that investing into PC hardware is not the glory to solve all problems. It is more likely to fix some problems to get other problems somewhere else. So the second part of the puzzle are the options and I guess to optimize the graphics options has more impact on the performance than any Euro you spent.

Also this doesn't take LOTUS and its optimization out of the equation. But vice versa nobody with an average PC should play LOTUS with bunch of heavy stutters. You may have to reduce your graphics settings for a time. And last but not least there is no need to play on the maximum graphics settings. Beside that the presets are only presets and have to be adjusted for the best performance on your special system.

So let's jump into the video:

I partially skipped through the video while you were driving, but I've seen a quite stable FPS around 30 (which is quite ok regarding your settings), but there are tons of stutters when reloading. If you have a second monitor, you can put the Task manager on your second screen to watch the usage of your hard drive, LOTUS is installed on. If I'm right, there should be spikes in the diagram when a stutter occurs. To minimize them, let's go through your settings:

These 3 settings are a bit over the top. As we currently got mostly tram routes, a max visibility of 1000 m for buildings is enough imo, 500 m should be enough for trees. The settings for 3D trees can be set to the second lowest setting on the left.

The first slider defines, when the max resolution of the scenery is loaded and for now this setting gives me headaches some times. I would recommend to put this setting more to the left, to decrease the stutter. The terrain detail slider can be set always to the left on "low", because it is not needed yet, because the maps are mostly flat.

I hope this reduces the stuttering without having much impact on your graphics.

Maybe it's a little fault in the Map itself. We are currently preparing a performance update, because we/I build less performance-friendly.

For example: the trees around the Map are all from Vegetation by BLV. This trees are beautiful, but also more detailed. So we decided to switch them with trees by Florian. There are beautiful too but considerably better in performance. Also my building style was at the beginning very unclean. For example: there are a lot of too big polygons and also splines with a length over 100 m. So it is recommended to build with smaller pieces to increase performance. This is all on our ToDo List so maybe try out another Map to have another reference.

P.S. Thanks for playing our Map

Please mind: This point has nothing to do with the final performance of the map itself in simulation. You should avoid big polygones and very long splines to increase the performance of the terrain generation in the MapEditor. So you will benefit from this correction as map developer, but not as player.

Oh, okay. I thought that would have a strong impact on the final result of the map, especially for the players.

Thanks for the correction.
