First Impression: Rfactor2 Formula Renault 3.5 at Sepang, 1440x900, HDR, in game AA Level 1

Software: rFactor2 Beta Version 1.005 build 49.
Processor: AMD Athlon II X4 635, all four cores Overclock: 3.3GHz, 4GB-763MHz DDR3 RAM
Video cards: ATI HD 5770, no AA, no AF, Overdrive: 890MHz (GPU) and 1320MHz (DDR5 VRAM)

At 1440x900, with HDR on, in-game AA Level 1, the average frame-rate is quite low: 34.600 FPS, measured with FRAPS 60 seconds benchmark. Turning off the HDR and in game AA, FPS will jump to 43.067.

However, at 1440x900, no AA means unpleasing & ugly scenes. The jaggies can be clearly seen on track's white side line and on fences and armco, sometimes on dashboard and other car's body line. The opponent's cars will look blurry most of the time, as if you were playing the game at 800x600 resolution, even though the actual screen resolution is 1440x900.

Turning on in-game AA level 2 or level 3 plus HDR will absolutely give you awesome scenes, but at the price of dropping down the FPS further, around 8-20 FPS, thus render this otherwise great racing simulation, unplayable.

Based on reports/posts at ISIforums.net, this problem happens to nVidia and ATI cards. Mostly affected are of older types. Amazingly, some SLI and CrossFire users reported to be affected as well.

Some forum users "fix" this problem by upgrading or overclocking the processor (3 GHz is minimum). Other forum users fix this problem by tweaking the ATI graphic setting and also by playing around with graphic-related setting found in the rFactor2's .PLR file. Other users reported that turning off car mirror improves the FPS by as much as 10 FPS. Others simply using higher resolution, minimum 1920x1080, with no AA and no HDR. But the performance or ugly scene problem is still exists!

This graphic bug is very annoying. rFactor1 is also suffering from this problem actually, but it can be fixed easily using 4xSSAA or using (minimum) 1920x1080 resolution with smallest or no AA, and the FPS is still able to reach way above 50 in most cases. My system can run rFactor1 at 1920x1080 with 4xSSAA. The minimum FPS is 60-65, and display setting is at their highest value!

Hopefully ISI can fix this graphic issues when rFactor2 is "going gold". The public beta phase will last about six month, January to June 2012.

You can download and purchase the beta from rfactor.net.
