Maybe it is the term "Hardcore mode" which makes people dislike the options suggested? I did not actually even think about it earlier but of course it is nothing HC if you are forced to use certain kind of controls and race procedures. In other words, the HC mode should be the closest thing to real life simulating all possible factors and disabilities. Whether it is ok to say that this, actually quite limited, virtual reality is hardcore is a question that can't be answered without making certain presumptions on the hardware and software available. With current PCs we are totally missing G-forces. But it is possible to buy or build something that creates them. But still you are watching and responding mainly on what you see on screen. One can buy "virtual glasses" and virtually sit inside a cockpit. What about sounds? 3d sounds with numerous different kind of sounds for different events is required to to finally develop a situation where the origin of the sound is what is getting our attention, not the sound itself. With this kind of equipment are we closer to real life, or is there still something missing?
Yes. The software needs to support the equipment we use. But even if the sim looked and sounded 100% right would it still feel 100% right? Of course not. A sim requires to be used to with proper kind of equipment and this requires that these controls have the correct and "real" functions. These functions make the clutch pedal to work like a real clutch pedals, paddles work as they do in real life and H-pattern shifters etc.. A good sim doesn't require that you buy or build all real life car controls in front of your PC, there are aids which allow us to drive with just 2 pedals or without shfiter.
But the sim isn't yet a race sim, it is just a driving sim. To race, battle positions and make the right tactical decisions we need correct enviroment. This environment needs to support the the real life factors which are essential to for a racing sim. False starts, engine damane, rain and red flags. The list isn't endless but it includes a lot more or less important features and options than at first glance it would seem.
All of these options and features come with limitations. One may not have 3 pedals, other can't race in rain because the FPS hit is unbearable. This is why a good sim offers options instead of rigid forms of HC modes and whatnots. People want to do what they want to do in that sim. Whether it was to simulate 24h races, crash racing or something else. Again, to suppport these different events, we need options. What is so different when an options is offered to to (theoretically) limit participants to use some special kind of hardware? Making a league for people using 3d sound only isn't really a good idea and offering such option is obviously just stupid. What about offering an option to "force" participants to use clutch pedals and shifters? It does not guarantee better racing, closer racing or cleaner racing. But it (theoretically) guarantees that everybody is using similar equipment. It theoretically guarantees that all people on that server have the chance of making similar errors. It goes without saying that driving with or without h-pattern shifters and clutch pedals makes 10000x bigger difference than with or without 3d sound. But is it fair to offer such options which are meant to divide people? Is it about dividing people into 2 groups, one has something, the other don't. Or is it about bringing together people with similar dedication and equipment?
Imho, HC mode does not offer anything interesting in itself. It just doesn't work in practise. What works is to give users the option to run the sim how they like it, within reason of course. Looking at LFS , it should offer as realistic experience as possible with the normal settings. This normal "mode" includes false starts, clutch supports and engine damages etc.. With options we could change the start to rolling starts with or without formation laps, disable midrace join, limit camera options and limit the use of driving aids and allow people in only with certain types of controllers. These are all just simple options for the server admins who want to set up their servers as they please.
Should one be punished because he/she is using "lesser" equipment? Should one be slower with paddles if the car wants H-pattern shifters? I say yes. It is not a question about money or skill, it is a question of seriousness towards the hobby, level of dedication. People who have either bought or built their own cockpits with real alike controls are dedicated with their hobby and want to use their hardware. In the end, should the use of aids be penalized instead of use of certain hardware?
