    1) It is legitimate to want to play in good conditions at night, at sunset, at sunrise, at low sun.

    2) It's legitimate to want to play in all rain conditions.

    3) It is legitimate to want to play with the maximum number of AIs allowed by the track, the 24h Nurburgring arrives, it is inconceivable to use less than 80 AI along these 25 km.

    4) It is inconceivable to have a relatively high-end PC, and to have to drop the graphics excessively in order to play in the real race conditions : the real racing conditions are the random combination of the rain, the whole day/night transitions, and an AI number actually corresponding to reality.

    @patchedupdemon wants to play in favorable race conditions for hardware, I want to play in realistic and random conditions, which justifies my performance test. But he doesn't understand that.

    Improved graphics should always go hand in hand with performance optimization, IMO

    ....... have fun with 30 AI for 25000 meters .....

    1 AI every 850 meters, what fun !!

    In real life the 24h nurburgring welcomes more than 100 cars: simulation or not simulation ?

    Racing ai isn’t fun I agree,and isn’t simulation just following a train of cars, but seriously, which sim with the level of physics that rf2 has, allows the use of 80ai, what’s the performance like.

    @DrivingFast
    i have a feeling that 61 AI is just traffic and not racing but thats just my opinion
    as for the results of your test i v tried your settings and had different results in rain on clear sky
    i believe shadows is the key when speaking about performance
    i manage to have 21 minimum fps 6.30 in morning at rain 12 hours sebring track with your settings.
    but it was playable
    when looking at minimum fps doesnt means that we always run in minimum
    minimum is mostly the fast corners
    moments in race that game demands insane power to give you smooth fps

    60-100 AI ? My question is why ?
    If you want to see cars on the track, start from the back of the grid and race forward.
    AtlantaMP is only 2 miles (3.2186 km), 50 AI could get kind of busy !
    Entry grid numbers for the following race was :
    2018 12 Hours of Sebring 43 cars

    Do not focus on the number of AI in my test :

    I do not have the exact number in mind, but I did the same test today with only 30 AI, almost the same settings or maybe exactly the same settings, and my minimum FPS was as I recall at 45 or 48 FPS maximum.

    Frankly this is not enough, it equates to about 53 FPS about average FPS, from what I could see. This is not enough for me.

    I persist in saying that there is a major performance problem in rF2. It is incomprehensible that some users do not realize it.

    More users will defend the alleged "good performance" or "acceptable performance" of rF2, minus the direction of S397 will want to cash back their graphics engine.

    Keep up guys, this is not in our interest.

    I only really need to have a car in front and a car behind so I if I set the AI strength properly I get away with 19 Ai cars and never not have the car in front and behind for any race on any track! Having 80Ai seems excessive imo.

    If you check my posts I’ve never said rf2 hasn’t got performance issues, butt aa level 5 with the rest at high or max with 30-100 ai in rain also, is expecting too much.

    You know we know, everyone knows rain and ai are FPS killers in rf2, maybe if S397 dumb down the physics and tyres then you could have your magic expected performance

    I’m still waiting for reply to which sim allows 80-100 ai at night with rain and has good performance

    I’d like to make my bmw 330ci make 1200bhp, without rebuilding or swapping the internals,but I know it just won’t happen, being realistic about expectations is the key here that’s all I’m sayin

    I think it's fair to say that rF2 has performance issues with 60-100 AI, but then again there is a reason why most sims won't let you add more than 20 AI. With these high-poly car models, the number of draw calls etc. increase rapidly with every AI car you add. At certain number of draw calls, the performance starts plummeting even more rapidly, so you might lose relatively more by going from 30 to 40 than 20 to 30 AI. PCI-E limitations might come to play here as well.

    A simple test to understand the huge impact of AI cars is to run an older open wheel model like Formula ISI, which has much less detail per car. In order to run 100 AI, I think either quality of car cockpit or FPS has to suffer. Maybe rF2 should allow an option like in Raceroom to run the AI cars without cockpits.

    There is an option on the player.json! I will test

    Yeah that's a very old option in isimotor, unless you are going to do a driver swap you can turn cockpits off. Would be nice if they made this work with swap, if cars had a list of drivers that are part of the entry so when we get in the server only that cockpit would load.
    Not sure how this helps fps in rF2. I remember it had a impact in older games.

    I've been trying to figure out exactly what it is about rain that cuts fps in half. So far the only conclusion I came to is that the harder it is raining, the worse the fps get. When it stops raining, fps come back up to normal, even with lots of puddles.

    Whether track has puddle map or not, it's the same percentage drop. The graphic setting for rain at Off, Low, or Max had very little effect, so using Low at least lets you see the raindrops. fps scales with number of AI at the same rate whether it's raining or not.

    You do realize that the minimum reported fps is the worst case scenario, right, but since you don't provide full settings nor provide average and maximum values there is no way for me to validate or recommend changes.

    Not on my system. I see big difference between rain off and low even on dry weather

    I also have a GTX 1080.

    For information there is a really noticeable difference between rain high and rain ultra in term of FPS performance.

    It is easily verifiable.

    And I do not agree at all with people who say there is no difference between rain high and rain ultra, and PP high and ultra PP in terms of graphics quality.

    I see a real difference in cockpit view and yet I'm only in full HD ........

    Woo-hoo! I improved the minimum framerate by over 30%!

    Accidently discovered I was being thermal limited on the GPU, so created a custom fan curve and got a significant improvement with no thermal limiting. Still, my minimum framerate in rain with GT3 AI is unplayably low.
