AI headlights are an fps killer in VR

[Gunsmoke301]

I love this game in VR but please give us the option to disable the headlights in heavy rain or dusk for the AI opponents as its a total fps killer.

Its not a problem at the back of the pack but once you get a few cars ahead its like a slideshow even with decent hardware.

I'm guessing its an optimization issue as I don't remember having this problem before the updates.

Yep, it's been mentioned in the Reiza forum. Hopefully, they listened to feedbacks. Headlights are unnecessary for daylight rain.

This has been a problem for ages and nothing done yet to try maximise the frames. The thing we have going against us is , like mentioned in the forum's, how many per cent actually use vr as this seems to be a deciding factor is what gets worked on. In other words.. Don't hold your breath.

You're not racing in VR. To save frame rate, there should be an option to turn it off.

There are a few settings that can tip the performance one way or the other, specifically with rain races (regardless if they are night or day, but rain and night will be the worse performing combination):

* Environment Mapping
* Reflections

These are two that play a big role in how things are reflected off wet surfaces and how much detail. If you haven't tried lowering those, give it a shot.

So is grass and shadows. I wish they also fix the shadows in VR.

I have Rtx 3900 an 12700K : in VR with 15 cars on grid by rain, all settings to minimum not possible to have 90 fps when more then 6 cars are behind you, tried Project Cars 2 with 15 cars all settings to maximum only shadows minimum stable 90 fps with all cars behind me. It is a problem with the headlights! Also the stuttering bug when you come to change tyres in VR and in 2D here mentioned for now ower 2 years….nothing happened !? ( in Projects cars 2 no stuttering all works fine )

This has been there since beginning I've stopped playing AMS 2 completely due to the wildly inconsistent performance and polish. Each track and/or weather condition can completely mess up framerates.

Turn off shadows and I mean completely off. They are fps killers when driving in the dark. Even just setting them to low causes a crazy amount of stuttering. Project Cars had the same issue.

Project Cars 2 had not this problem !

I have both AMS2 and Project Cars 2 installed on my computer. I play them both in VR. Both of them have the same issue with shadows causing a massive drop in fps and stutters when all of the cars have their headlights on.

There is still some drop in performance even with shadows disabled, but it is nowhere near as bad as when they are enabled.

Turning shadows off was the biggest performance boost I got in both games.

Agreed, but I was referencing the issues with rain. Grass and shadows are performance issues outside of rain as well.

For what they are, shadows can be pretty complex. When you add in multiple light sources (headlights) for the calculations, you end up with a lot of CPU and GPU effort constantly when the shadows are dynamic.
