На форуме Beyond3d выложили updated файл interaction.vfp
Дома проверил - действительно игруха стала заметно быстрее. Теперь можно даже при 1280х1024 на high настройках играть почти без тормозов.
Процедура проста: скопируйте следующее и вставьте в блокнот, после чего сохраните файл как interaction.vfp.

После этого надо открыть с помощью WinRAR файл pak000.pk4, удалить файл interaction.vfp в папке glprogs и вставить новый, только что сохраненный interaction.vfp на его место, после чего ответить Да на запрос WinRAR об обновлении архива.
