Video game development is rarely about one man, but if it was, then Terence Groening should certainly get a mention for his contributions to the genre as the man responsible for the physics of Sportscar GT, EA’s PC F1 and NASCAR games of the early 2000’s, rFactor, rFactor 2 and every title and rFpro simulator that spawned from ISI’s engine.
This interview with RSC details his early life and career, through to him joining iRacing in 2021.
Originally working in military simulator design, this Michigan-based studio developed Zone Raiders for Virgin Interactive before moving to Electronic Arts for publishing their second PC title, Sports Car GT, when Westwood Studios (their SCGT development partner) was acquired by the software giant.
Known primarily for their mod-friendly SCGT and rFactor racing platforms, ISI also developed Formula One and NASCAR titles on PC for Electronic Arts, but perhaps their lasting contribution to the genre was the licensing of the isiMotor engine that allowed studios such as 2Pez, Blimey! Games, KW Studios, Motorsport Games, Reiza Studios, SIMBIN Studios, Slightly Mad Studios, The Sim Factory, Tiburon and rFactor 2‘s ongoing developer Studio 397 to begin with or release on an evolution of their software.
Another fork of the isiMotor engine, rFpro, continues to be developed and is used by a wide array of automotive companies for both road and motorsport simulation.
Join Jon Denton, Tim Wheatley, Simon Croft and guest(s) as they discuss sim racing and racing games past, present and future.
The latest patch for F1 25 features quite a long list of fixes and tweaks to tackle player reported issues with the title. Check out the notes below.
v1.03 Patch Notes
Highlights
Fixed an issue where visual effects of light rain were incorrectly represented, resulting in damp conditions appearing dry
Some players had reported that during a race, the car would begin to feel as though it was driving in ‘light rain’ conditions, however, the weather conditions did not reflect that. Visual weather in these instances now better reflects how the car feels.Fixed an issue in Driver Career where the Konnersport and APXGP teams were receiving an unfairly large amount of Resource Points
For existing saves, incorrectly accrued Resource Points won’t be taken away but Konnersport/APXGP will now earn points at the normal rate, balancing out compared to other teams over time. New Driver Career saves games will work as intended from the start.Fixed an issue where with HDR set to On, the Gamma slider was locked
HDR setting will now default to Auto (PS5 & Xbox Series X|S Only)
To enable or disable HDR on console, please do so in your console settings rather than in-game.Updated build configuration to enable Intel XeSS Frame Generation (XeFG) on compatible hardware (PC Only)
