Guidance for increasing frame-rate

I'm struggling with my setup, new to drive/racing sims and only been flight-simming up to now.

I have a new PC with an i12900K, RTX3080ti and 32Gb ram in it - I thought this was fairly good?

The screens are are just triple 50" HiSense 4K panels, 60Hz with low-latency gaming mode turned on, configured in Nvidia as surround.

Since trying BeamNG i've been finding it causes a fair bit of strain/motion sickness feeling when cornering fast etc, the FPS counter shows I'm somewhere between 20 and 55FPS avg and this is on "Normal" graphics setting.

Lowering to "Low" setting gets me up into the high 50's and things seem pretty much usable but naturally it also looks poor.

I have also tried Euro Truck Simulator and found similar when cornering at any speed - it gets very uncomfortable.

Is it possible I have an issue with my setup as I would have thought it should perform better? In MS Flight sim I can configure the panels individually so I run it as 2K - 4K - 2K and its usable at 30FPS but things move a lot slower in a plane.

Any tips I can check???

 

Do you have traffic enabled? It tanks your performance if you have too many cars

 

At present its all pretty much default and I have not seen any other traffic at all, I have only tried two free-roam tests, one on the track and one in small-town USA, no traffic visible.

 

Your PC is very good, but running 3 screens at 4K is super intensive. I think triple 4K screens might be just too much for your GPU to handle at high settings, high framerates and full resolution in this game. Naturally, that is less of a problem for slower paced games like you have mentioned.
3x 4K is 12 times more pixels than a single 1080p panel which most regular gamers are using.

 

Since posting I have done a whole lot of watching, reading etc, much more than i originally did - we all make mistakes right

I have now ordered three LG Ultragear 1440p 32" 144Hz 1ms screens and will sell off my existing 50" panels.

Prior to making this decision, I did some rough testing by lowering the resolution of my 50" setup to something near a 1440p setup, the difference was night and day, much smoother, easier to drive, no eye/head strain effects. Naturally the pictures looked rough at this setting on such large panels but all i wanted was the rough pixel count to test the GPU. It was firmly pegged at 60Hz which is the limit of the 50Hz panels so any amount over 60Hz will be even more benefit but I can't see what that will be yet.

I'm currently remodelling my mount setup to cater for the smaller screens and closer position.

 

Just disable VSync, then you will see how high the framerate goes
