The issue is coused by
CLUSTER_THRESHOLD = 5
in [LIGHT_SERIES_...] section, which creates too many lights
Expecially for the Stands meshes which are large

Learn something new every day! I updated Riverside that uses fewer lights by manually replacing it with more wider range lights instead of relying on light series codes and increase the CLUSTER_THRESHOLD to around 18. It should be less impacting on performance, also made few overall changes.

A very simple light configuration for Riverside UPDATE: More track side lights and less impact on performance. Please re-download if you have an earlier version.

Damn, I was looking for this skin yesterday. Glad someone made it.

I didn't tested your version, but, since i made a lot (very very lot) of configs, what i always noticed on my system is that

  • Cluster threeshold impact a lot on performances (a value of 12 is enough to reduce fps impact, higher i never noticed any changes but it worth a try)
  • The dimension of the area, impact almost in the same way. So if you put a light with an a range of 300 it will impact the same way as a few smaller ones with a lower cluster value

Balancing night lights (when you have real light sources is always a pain), when you don't have them, could be even more even if you don't care that much about realism since of course, if you don't have sources, you should not have light.

Hope this helps a bit
 
I love these explanations that shed light (pun intended) on optimization issues that drive my simian brain crazy, like why there are great mods that perform well at night and others that seems very similar, suck...

I'll be just as screwed because poorly optimized mods will continue to suck in certain circumstances (until some kind soul fixes them), but at least I'll know what's screwing me...

I just want all previews to look like the camera hasn't moved, and that every car is always centred the same.
Lock camera in preview window means what exactly? The preview window is a blue crystal mess with planes cutting through the car. Not useful at all.
World space? Screen space?
Rel? Rel what? Religion? Relativity? Relocation? Relationships?

Using my personal preset I have found that leaving everything checked, except the "Rel." boxes leads to consistent placement... on most cars. But as you would expect with all things AC CSP, not all the time. Say 5% of cars, generally from more obscure modders, require an Offset value or values to get them re-centred.

Also hillclimb-monster size rear wings and rooftop aerials often require a vertical Offset value of say 5 or 10% to get the main body centred, if you have the 2 checkboxes ticked.

I believe "Rel." stands for 'Relative to...' So the Offset % value is not absolute but relative to the size of the car is placed depending on the "Position" and "View angle" parameters. With "Rel." checked the movement factor is far smaller if the car is zoomed in closer in the preview. When not relative to the zoomed picture adjusting the Offset % has a far greater effect.

My wish for a Previews improvement would be a checkbox that would allow the "View angle" to be automatically adjusted depending on the size of each car. Currently to keep all cars filling my Preview window as I like it, as per the attached image, is a time consuming labour of love. Or I could do the sensible thing and choose one view angle value that fits the biggest modern GT3 or Hypercars, and just accept that all the little 60's cars are going to be swimming in a big window of background image.

The lights at night are quite expensive (on not high end pc's of course), even worse if you combine them with rain. I have a quite extreme modern pc but, since i use if for work and not primary for gaming, my GPU is old (so i have a huge bottleneck), but this allow me to make my config easy even for low-end pc's.

If you have real light sources, you can (if meshes or materials are named properly) balance the performance and the quality of lights, if not is a total nightmare.

@samdale12, you seem to know your way around these CSP previews. Are you able to explain what these various parameters mean?
I dropped my crystal ball onto my Rosetta stone and I can no longer astral project onto Ilja's yacht to ask him WTAF he's smoking when he labels these things.
I've done a variation of your preview above but can't seem to get the background to stay in exactly the same position every time, or to get all cars to scale correctly first time.
Occasionally the background (or car) will shift slightly in the scene, or the odd car will appear huge.

I wish I knew!

  • With both 'In world-space' and 'In screen-space horizontally' ticked, the slider seems to move the car in the showroom left and right, while the camera stays fixed.
  • With just 'In world-space' ticked, the slider is greyed out.
  • With just 'In screen-space horizontally' ticked, the slider goes crazy and moves the car laterally plus the camera in some kind of weird parallax arrangement.
  • 'Rel.' appears to make the slider adjustment much finer.
'Lock camera in preview window' just seems to make it so that your mouse has no effect when clicking around in the 'Preview' window. With it deselected, holding down the left mouse button allows you to pan and tilt the camera, and holding down the centre mouse button allows you to truck and pedestal (using the definitions available here).

I'm afraid none of this helps with the problems you are experiencing - I do wonder sometimes if cars have been modelled away from the origin / 0,0,0 in the relevant 3D modelling program, and sometimes the Showroom is the first place that shows up 🤷‍♂️

Edited to add: there is another setting in CM you might like to experiment with 'Auto-adjusting camera pivot' - I usually have it on (but it could introduce variability like you are seeing).

Never understood why the lighting was so damn ressource intensive in AC compared to... Well any other games lol. Running night races in PC2, AMS2, LMU, Heat 5 ? 80+ FPS No sweat. Running night races in AC ? Get lost buddy, here's 55 FPS for ya.

Everything depends on the engine. The better the engine's code, the better the results.

That's why even AAA games use engines like Unreal or Unity. Some studios develop their own engines, but that requires a lot of work. The base engine of AC wasn't designed for features like rain or advanced lighting (which is why you need CSP), so anything you add to it takes more effort to make it run properly.

If you then add the fact that some tracks and cars are poorly developed, the result is poor performance.

Thanks for this, very much appreciated. I'm kind of relieved to know that I'm not the only one who struggles with the enigma of CM and CSP UI labels. It's like an exercise in illogical assumption every time you try to do something.
 
Coming back to tracks, since we're probably get the Singapore from Codies, could we finally have a version of Korea that doesn't suck ? The Codies version we have from ACU has so many missing trees in the background and the other one is a kinda inaccurate port from RF.

I'd love to see the F1 2010 version with all the cranes ;)

A simple way to debug lights:
  • go on track
  • open "CSP debug" app (under "developer apps")
  • select the "Lights" menu
  • enable "Debug lights" option

- press F7 and fly around the track and check the light yellow boxes

Yes but... why? I know my settings and all the 700+ config i made, works fine, i defined a system that give me less issue with a full config empty template. But then, the final result, depends on how the track is made with the light sources (i never add lights where there's no real light sources since i want a proper 1:1 version of the real track, as close as possible to the real counterpart).
 
Does anyone know of any (broadcasted) race event ever that was run on the Grand layout of VIR?

The Full layout sees plenty of racing, but I can only find amateur track day videos of driving on the Grand layout - and I'm curious to know if it ever hosted a proper televised race?

Just for the record: VHE Hockenheim is an amazing track with superb, flawless AI. I just had a race of my life in my 2002 F1 season. Whoever made that track, thank you. Drove with Montoya, 20 laps (one pitstop for all) against Raikkonen and Schumacher (ai 96 and 100). It was incredible. I was third, just 1 seconds separated these three. Great overtakes, amazing racing, all were clocking mid 1:17- low 1:18 times.. For whatever reason AC didn't save the replay. What a bummer.

AC AI is excellent when you have a perfect car, perfect fastlane, properly set AI driver aggression and you keep yout line in the overtake situations. Way better than its reputation.

VHE Hockenheim 13:57 on the video (ai driving, with my 2002 sponsors)

That's why we are hooked :D This is similar to the people who prefer Windows over macOS
