Exactly what I experience

Similar here: This latest build seems like an improvement, but the steering input lag isn't gone completely.

Testing the in-game Video settings, using Fraps to check framerate, lowering Reflection Quality from High to Medium gave me a +8-10 FPS boost. The majority of the other in-game Video settings only gave 1-2 FPS differences.

One odd result: Raising Anti-Aliasing from (my default) Normal to High gave a +5-10 FPS boost, but it had some strange visual effects - odd textures - and it showed as "_ON_" in the settings, rather than High, when going back to look at the settings. Something weird going on there. I'll leave it at Normal for now.

I guess this illustrates what's so fascinating about the WMD concept. On the one hand, we get access to bleeding edge development but at the expense of seeing all the bugs first hand. It also gives a refreshing insight into just how difficult it is to be a software developer. The great news is that SMS now have the words largest and most demanding group of beta testers. The steering lag problem is a prime example of how community feedback will cause them to eliminate a potential show stopping bug that the devs themselves admitted they hadn't experienced on their machines.

Took the plunge too. It's amazing, no other word. The attention to graphical detail is stunning :-)

I'm trying to find out what cars are offered? Will there be regular seasons such as Indycar and F1? Will it be online and offline single player?

The initial design document states Karting, Touring Cars, GT1/2/3, Formula Ford, Formula Atlantic, Indy Lite, IndyCar, NASCAR,Drift, Rally, Formula Ford, Formula One, and Prototype. None of this is confirmed yet. and the exact cars will probably be dependant upon licensing etc.

These will be designed into some kind of single player career structure for those who like that kind of thing. The career mode will be optional (and customizable) so no level grinding for those who don't want it. Obviously they will also be usable in multiplayer via an online portal or dedicated server option. The main release will probably include base content from all of the classes with more cars/track purchasable via one time micro transactions.

Once again it's important to state that NONE of this exists yet and will probably change several times before release - it's just a projected roadmap from the first brief of the design document.

Sounds like they want to give iRacing some competition or at least pull some of their road racing fans away. I know iRacing's biggest pull are the NASCAR sim fans.

The SMS guys are working late! 0.74 just sneaked out while no one was looking. Graphics bug fixes, track enhancements, performance tweaks, sound tweaks, basic replays and some more work on handling, FF and lag.

I have no more steering lag in the new version!

0.74 downloaded!

At first I thought lag is almost gone. Formula B at Imola felt great and I was able to push it hard this time.

Then I took other cars to Watkins and I felt lag again. Especially with Lotus68. When it starts wags its tail end it's just impossible to catch. Every correction makes it worse. I went to tail camera and started visious steering moves at low speed. And it's visible that after several moves of steering wheel left and right the lag builds up to amount that car is turning opposite direction where my steering input goes. And in car steering is also lagged in opposite directions.

Don't know... maybe I sm just lost here. Maybe such a car will never accept such a quick steering moves in real life as no human power is strong enough to counter mechanical restistant of steering mechanics and tyres mass innertia. Maybe that's why physics engine is not prepared for that?
