I marked the reference used for that contribution as "dubious" because it seems based on old source material:
- www-gta-ru.translate.goog/forums/gta_4/graficheskoe_sravnenie_gta_iv_xbox_360_vs_pc-928948/?_x_tr_sch=http&_x_tr_sl=ru&_x_tr_tl=en&_x_tr_hl=fr

- /gtaforums-com.translate.goog/topic/525004-gta-iv-version-differences/?_x_tr_sl=ru&_x_tr_tl=en&_x_tr_hl=fr
Also, the screenshots used are from an Xbox emulator which is scaling the 720p version into 1080p.
Finally, while it seems that some details are indeed different, the author did not specify (AFAIK), which PC setting they used. PC setting is important, because I noticed that "View Distance" and "Detail Distance" have an influence on the car lights and the street lights. Some comparisons in the reference might not use that knowledge. (Edited in order to fix a typo)
