I’m only bothered by one annoying flaw that I see a few times each gameplay session of FH4 (the same flaw
is in all previous Horizon games also). I recently posted the following product review on Amazon:
4.0 out of 5 stars Header: “Only one sore-thumb graphics flaw.”
December 2, 2018 Platform: Xbox OneEdition. Review text: “Forza Horizon 4, like the previous Horizon games, has about the best
graphics (scenery and car realism) of any race games available. It also has excellent car handling with the XBox One controller pad
(I haven’t tried a wheel controller, pad is fine for my gameplay). The races can be customized (blueprinted), you can choose time
of day, season, and weather. The only flaw that bothers me is occasional abrupt changes in a patch of shadow or light. Most
often it’s one or 2 trees, which you’ll see suddenly flash from light green to black shadow; half to all of the tree. That I notice
and get distracted, mildly annoyed by, a few times during each gameplay session. It can also happen on ground; an area
abruptly flashes from light to dark shadow or vice versa. All the previous Forza games share that flaw. I hope that
in Horizon 5 the studio designers could progress and get rid of those unrealistic abrupt switches of areas from light
to black shadow, or black shadow to light. Then I’d have nothing about the graphics to criticize. It’s not a substantial
problem, I ignore it - the game in general, 99 percent of the time looks great, realistic, scenic.”
I have found also one really annoyining graphic bug, some trees rendiring (im not sure is that right word for that) either really slowly or wrong. - YouTube It’s shown in that video in one minute mark when watching trees that are front in left side.
The problem occurs with the scaling of the time of day, as the time of day changes you visibly notice shadows from all objects jump to another position for the next few seconds during a full cycle, if the shadow transition was more gradual you wouldn’t notice as much. I think a day on horizon is about 35 - 40 minutes long I think a day on NFS payback is about 1 hour 20mins and you can really see the difference. It could also be that movement of the light source (sun) is incremental rather than entirely dynamic, so you easily notice each rendered set of shadows when standing still. I don’t stand still much
