Hoping for the patch

If you read the many reviews and scoured through various forums, you really think there are two different games.
It appears that the processing power in the control plays a decisive role in the performance and (IMPORTANT !!!).
Also the statement of the developer at the scheduled Patch that there was a problem in the thread programming:

"There was a dead-zone issue and a threading problem Introduced very late in development thathave been fixed." (Statement by Slightly Mad Studios)

I have on my Alienware M17x with NVIDIA 260GTX graphics card with a Core 2 Quad Q9000 at race a frame rate of 35 fps (1440x900 resolution). For me, this means a delay controller (both with Saitek R440 steering wheel as well as XBOX360 gamepad) of about 0.1 seconds.
The result is a very spongy ride, compared with GT Legends, GTR2 rFactor or what I really like and often games and where the control is very precise and direct.
On this ride you can get used to after a while, but for me it always has a bad aftertaste.

As far as my opinion, for the most criticism.

Otherwise, I like much the innovations. You can save his tuning for each car and each route separately. It has a so-called LIVE-tuning, where one (admittedly somewhat Spartan) contains statements about Reifentemp, load changes, torque and accordingly vote to be setup.
Replays can save and upload directly to YouTube.
The vehicle selection is in my opinion succeeded (except the absence of Ferrari).
Good route selection (Original Grand Prix circuit with variations such as Donington, Spa, Nordschleife).

Conclusion:
A good semi-Sim-Racer with (for me) control problems and therefore only 30 percent simulation claim, but still fun and gives hope for a good patch.
