The attached patch will make AI available at 60 fps. AI is not expected to work properly, but they seem to stay mostly on track and drive in the right direction    Read the readme, and if you have not already done so, also read the README for the original 60 fps patch. Report 60 fps AI problems here, and non-AI related 60 fps bugs in the 60 fps topic.

UPDATE: the 60fpsv2 patch makes AI available as well, so its better to upgrade to that:
http://srmz.net/inde...?showtopic=4584

Note that AI is only expected to be somewhat driveable for the original 67 only. Mods (including the not yet released 67 mod) change the AI in a way which is not compatible with 60fps, so the results are not good.

Thank you for this.  All I ask of AI is that they run at a reasonable pace, mostly finish the race, and don't bang into me too much.

That rules out the 67's unless you take out Surtees 1st  

[miklkit]

Naw.  I like the 67 AI.  Surtees is only nuts in the 1st lap.  He can't help it if that White Whale can't stop.  

Not a bug report or complaint.  Just observations of what you probably already know.  Ran some races at Rock Lobster's Watkins Glen in the Lotus 49.  40fps bog that went up to 60fps in a few seconds.  The AI pace was good for most drivers, with the pole at 1:06 + or -.  There was no passing, so the races were parades.  Sometimes the AI seemed to be afraid of their own shadow and jumped off track for no good reason.  Damaged cars sometimes behaved oddly.  Pass with care.  They cornered well and accelerated normally, but didn't seem to have good top speed.  Overall, I've seen much worse.

Thanks brr. I can't wait to get home and try these!

[ezechiel47]

Many thanks for that marvelous patch. Now i don't want to play any more without it !

Ive made some laps at silverstone (original AI) with gpl 67 and syracuse (personnal AI) with 66'mod. But not yet a complete race.

I'm happy to say there is no big issues !

AI behaviour is coherent (so far it's possible in gpl). Lap times are correct. Drivers'hierarchy doesn't seem to be really affected. And on my installs, AI can pass each other without any problems.

One thing however : it seems that specially when they pass or try to pass, AI have a behaviour a bit too abrupt. Acoording to me, they also tend to pass too often, they change the line too often (like said Miklit).

But these are only quick considerations after a dozen of laps.

I went to Torino and Clermont Ferrand last nite.  At Torino the AI are better than the other 2 I've tried there.        I even had a nice dice with Surtees, passing and repassing until I finally made it stick.  Then stuck my Brabham in the haybales....  That track is fun and challenging in the 66's but devilish in the 67's.  

At C-L I kept crashing, but let the AI finish.  Best time: 3:20, 9 finishers.  Is that good for 67?

3'20" is correct (but it depend on your driver.ini and your track.ini, on my install its 3'22"). 9 finishers it's not enough. AI are a bit weird. I test some tweaks in the gplai...

I have never touched the 67 AI. I always liked them the way they are.  

Yesterday I went to Spa, figuring their lack of speed would really show up.  Wrong!!  They ran just fine there.  The backmarkers were slow, but the fast guys are still fast.  

Next was Rouen.  I set a new Brabham PB there.  Didn't see any odd behavior there.

Then I tried Zandvoort because I had recently spent some time there.  There was a 3 second spread from 1st to last.  That made for heavy traffic.
Then, thinking about EZ's comments about the 66's, I tried the 66's there.  They worked!  But I had messed with the AI there and they were weird.  There was a 14 second spread, which is good.  But most of them topped out at 120mph (200kph?).  I saw the AI passing each other for the first time too. Later in the race passing lapped cars was the issue.   Their laps were in the 1:31 to 1:45 range.  The AI couldn't seem to make up their mind what to do when I showed up behind them and wobbled and darted all over the track, often bumping into me.  But that is a bad track to look at them because of my tweeks.  Oh, my 36fps 66 McLaren pb there is 1:29.96.  At 60fps I got a 1:29.97.

I would not expect too much from 60fps AI with the mods. From what I understand, mods change the AI and there is currently nothing in the patch to take this into account. The result is either that the patch overwrites some mod AI parameters, or mod AI overwrites some of the 60fps AI parameters.

[miklkit]

You are right.  I just tried the 60fps patch on the 66's at Monza.  They were hopelessly slow.  Unchecked the box in GEM and they were their usual self again.

[sky]

doesn't seem to affect the '69 mod that much. i'm running at 1.85-2.0 in the ai adjust thingy, and there's some that are quite fast, but not unrealisticly (i used to haev the ai setting at 0.5 and they were doing 52-55sec laps at the glen , doh) so. it's times i could eventually equal given enough practice. but there were quite a few that were slower than me - but that's ok too.

as someone already noted sometimes the ai drives rather slow. especially in groups of 3, hardly overtakin. i tested this in reims with the long backstraight, no overtaking on the uphill stretch but sometimes (after trailing the entire straight) they would pull out right before the turn, where they would get into my approach (and i would have to take the um emergency exit)

still i prefer all of this over having to bear with 36fps

[jklhill]

69 at the Glen seems good. Some abrupt line changes that I am sure can be fine tuned with the ai_ini. I found them quite enjoyable. And 60fps   Thanks to everyone involved!

Excuse me,but i have not understood.This AI is also for 66 ,65 ,69 or only for 67?

It seems to run with the mods, but probably not as well as with 67.

The suggestion is to apply this AI to the 67,on the other mods is a test?I know that there is a difference betwen the Ai of 67 and 66,69,65 especially in the behaviour of the pilots.In the 66mod they are to aggressive in closing the path for example.

"60 fps AI for testing" is the topic title, so consider this a testing version in every case. Try it out and see if it works well enough for you. Its easy to install and uninstall.

OK,thank you

[mdw1961]

A huge thanks to brr for this and all the other fabulous developments he has brought to GPL.

Just run several races against the AI at Monza and Silverstone and all seems well to me. The odd abrupt line change but nothing drastic. Superb!

Now we just need GPLRA "cracking" for 60fps.

Happy lapping
