guys maybe some 2 hours races with dynamic weeather and finishing in dark
Indeed, I mostly leave the dynamic weather at default. (29° Sunny). But dynamic weather has an influence on the setup, tire wear and lap times.
Last year there was a real life (Belgium historic cup) race at spa. Temperatures were near freezing and it was dry and sunny. Almost everybody did there personal best lap times at Spa that day. You would expect very low temps should have a negative influence on grip. But it didn't. Tires didn't overheat that quickly, It was very welcome for the big V8's. They were alway very fast at the beginning of the race. But dropped back halve way the race. And the cold air temperatures had an positive influence on engine power too.
At most mid-europian race tracks, 29° and sunny isn't realistic. (i wish it would ) This doesn't mean it is raining all the time. But more realistic weather like 15°-20° with some clouds is something we could do more often.
