Update v1.3.4 Hits Assetto Corsa

v1.3.4 of Assetto Corsa is out now, and not only brings further bug fixes from the v1.3 update, but some interesting new features.  A few that fall under the category of “interesting” are the GT2 and GT3 tire updates, the allowance of leagues to add ballast to GT3 cars and the upping of the replay ceiling from 500 MB to 1 GB on x64 systems.

The rest of the changes – including the v1.3.3 update from October 17th – can be seen below:

1.3.4
– Replay in x64 are now capped at 1Gb instead of 500mb
– Fixed turbo in form gears
– Physics multithread is now disable with less than 4 cores
– Fixed backfire animation on Lamborghini Countach
– acServerManager: admin password is mandatory
– acServerManager: fixed uploader not saving surfaces.ini of multi-layout tracks
– Fixed Lamborghini Countach S1 UI for customers who do not own DLC2
– Fixed Alfa Romeo 4c peak slip angle value on rear street tyres.
– Fine tuning of tyre heating model for GT2 and GT3 cars. Tyres now might need 2 laps to heat up the core temperatures. Core temperatures are now much more stable during a lap and cool down slower.
– New power loss calculation for GT2 GT3 cars engines
– Corrected rolling resistance calculations for GT2 and GT3 cars tyres
– BMW M3 E30 Drift and M3 E92 drift has new tyre heat calculation following the GT2/GT3 logic. Experimental.
– Balancing of GT3 car performances. The balance does not make all cars equal, but just brings their performances closer. Leagues can now add a small amount of ballast to equalize the cars performances even more.
– Fixed dirt texture and headights in Ferrari 458 Italia
– Fixed headlights indicator on BMW Z4 GT3
– Fixed transparency issue on Ruf Yellowbird
– Added leds to Mercedes SLS GT3
– Fixed TrackIR support for x64
– Added Force Feedback Controller app
– Fixed acServer corruption of internal buffers leading to packet losses
– Added benchmark mode
– Realtime app now uses magenta to signal fastest lap in the session
– New “camera facing” spectators are now controlled by the “world detail” settings. Allowing users with older machines to achieve better FPS
– Minor AI race craft tweaks (a bit faster to change lane but bit less “punchybumpy”)
– Remapped some functions associated with numpad “+” and “-”
+/- = Change Force Feedback (disabled in replays)
Ctrl +/- = Change onboard FOV
Ctrl Shift +/- = Change saturation

1.3.3
– Fixed wrong timing in brake disc glow effect
– Improved AI spline road sides at Spa
– AI spline sides now accept CSV with both “,” or ” ” as delimiters

– Direct Input devices are not initialized with a BACKGROUND flag instead of FOREGROUND
– Set audio channels to 128 instead of 64 in audio.ini
– Added turbo boost information to shared memory
– Fixed tyre vertical stiffness pressure dependency wrongly using ideal pressure instead of reference pressure
– Fixed upshift audio sample not correctly triggered
– Fixed Ruf RT12R limiter audio clicks
– Minor EQ tweaks
– Rebalanced heat distribution as function of camber
– Experimental heat/grip ratio for BMW M3 E30 Drift, BMW M3 E92 Drift, BMW Z4 Drift
