Most boring F1 tracks (in all sims)
Monaco.
In every F1 season I play this is just so annoying. When I started sim racing like 20 years ago it was cool track to master but it gets really old after a while. I'm sure the real drivers feel the same way... overtaking almost impossible and on AC the crashes often create many issues (like traffic jams) because of the dumb AI. On F1 2020 and 2021 (great F1 games that I regularly play) the AI is superb but driving the Monaco race is almost always very boring. Basically just to avoid mistakes, not real racing.
Hungaroring
Never liked this track. For whatever reason this was always the one in the vintage AC F1 seasons where the ai was super slow. Then Thockard made new AI it and made it so much faster. But it's a bit boring track, overtaking is only possible on the first corner after the long straight. That's actually realistic as it is that way in the real track too. Never liked Hungaroring.
Jacarepagua
Maybe because I've driven it endlessly as I used it as a "test track" when I built my vintage AC F1 seasons. It was almost always the first race of the calendar. But it's not that interesting circuit to drive anyway.
Valencia is quite bad too and of course Detroit street circuit and 1982 Caesar's Palace (officially the worst track ever). Old Hermanos Rodriguez isn't that great, new Mexico track is much better. Old Kyalami isn't that enjoyable, either. 1992/1993 version is okay. We have very good conversions of these tracks, we even have Detroit 1982 with that extra chicane.
Most enjoyable:
Spa, Monza, Imola, Suzuka, Interlagos... we all know how great tracks they are.
Portimao
This is one amazing and super enjoyable track to drive. I only discovered it when I recently got F1 2021 (finally). The layout is so enjoyable and the races are great. How on earth they're not having this race in the F1 calendar anymore. This is one of the best F1 tracks ever.
Singapore and Baku
Among the best street circuits, both are challenging but when you find the rhythm, I've had some amazing races in both.
New Hockenheim. Had some great races on AC seasons in the new Hockenheim. The old one is very boring and long circuit, it's basically just about top speed.
Adelaide
Singapore and Baku are great but for whatever reason I enjoy Adelaide the most (of the street circuits). It's such a legendary track and it's a shame that it was removed from the calendar a long time ago. Melbourne isn't bad but Adelaide is THE Australian track for me. Quite long learning curve but when it "clicks" it's so amazing. So many legendary real races here as it was the final race of those vintage F1 seasons (like Mansell's tyre explosion in 1986) and I've had my share of great Adelaide racing on AC too.
Dijon
This little known masterpiece by Rainmaker is very cool piece of F1 history. Weird GP as it was called Swiss GP but Dijon is actually in France. I think it was because motor racing was banned in Switzerland (maybe it still is, huh). It's in my 1982 and 1984 F1 seasons.
4:18 in the video.
Hardest track is probably the Phoenix street circuit. I've practiced it so much but the walls are so tight in that circuit that surviving a 25 lap race against Assetto Corsa AI cars is always a challenge.
1:00 in the video. Those 1990 RSS cars are utterly amazing. Skins only though but that's why the season is so trouble free. Definitely my favorite vintage F1 season on AC being a huge Prost fan... and Prost almost won the title with that Ferrari (we all remember what happened at Suzuka with Senna hehe).
The tracks and AI's we have on Assetto Corsa F1 tracks are quite amazing indeed. Now that even Dallas 1984 AI got fixed by
@IMEAN there aren't many problematic tracks anymore. Give it a shot, link in the video description. The real track itself isn't great at all and they almost cancelled the GP because the track surface was so badly damaged... and it was hot like hell that day. But the actual race is one of the best GP's ever. I think 7 different race leaders and Keke Rosberg won the race with his crappy 1984 Williams (it was truly horrific car, even Patrick Head admitted that). Check the AC track and the real race... so cool F1 history that we have on AC (like Dijon, Caesars Palace and Dallas). Yeah the cars aren't great (modded SD) but beggars can't be choosers.
List yours.
