LOD issues with large grid (plenty of VRAM headroom)

Product: GRID Legends
Platform:PC
Summarize your bug Object pop-in and late LOD transitions
Please specify your platform model. Origin
Did you have cross-play enabled? No
In what game mode did the bug occur? Offline Career
How often does the bug occur? Often (50% - 99%)
Steps: How can we find the bug ourselves? Race San Francisco (and many other tracks) with full grid
What happens when the bug occurs? Trees, buildings, etc, transition to high LOD very late
What do you expect to see? High detail objects appearing earlier (race same events with 10 cars or less)

See video https://www.youtube.com/watch?v=6v-bBhx2YOI

Note the buildings remaining low LOD models until very late. Also happens with trees on MANY circuits. Is very noticable and jarring/ distracting. This is not a VRAM issue. Using 8GB/12GB on my 6700XT. Is much less noticeable with smaller grids

    Hi @BenBRogue Thanks for letting us know about what your seeing in GRID Legends, can we try the following to see if you continue to notice this?

    Thanks!

  • I've updated to the latest version (via EA App (also tested Origin). Tried those solutions you mentioned for both EA App and Origin (also tried re-downloaded the game), still having the same LOD issues for buildings, trees, cones and other objects (cars and debris on track too) on highest settings on many (if not most) tracks.

    I initially thought it was just a problem with large grids, but even with just two cars it happens every time for me. These LOD issues are NOT LIMITED TO THESE TRACKS / OBJECTS or even settings. It might be less noticeable or unnoticeable gaming at a distance or on a smaller or lower resolution display, but I game at 4k on a 42" monitor at a desk (about 1m from the display), but even when I had a different GPU and a 1440p 32" monitor playing GRID 2019, these issues were present then. The LOD transitions on some objects is just very low even on high. It doesn't seem to be a hardware issue, as I've seen these same issues in videos on YouTube from reviewers and "influencers" also. The LOD's for objects need to be combed over and extended, or an additional "Ultra" setting needs to be added to push that LOD transition out two fold AT LEAST on many objects. Gone are the days where an .ini edit was the solution 😢

    Here are a few videos (please view in 4k where available as the compression is really awful):

    Cone pop-in (all tracks with track-side cones) https://www.youtube.com/watch?v=rJkTwfniyM4

    System specs for reference:

    Red Devil Radeon 6700XT 12GB

    Ryzen 2700X (8 core CPU)

    16GB (2X8GB) 3200MHz CL16 RAM

    Game installed on Samsung QVO 4TB SSD

  • Speaking of .ini edits, I actually found a temporary workaround for the trees and some building LOD issues, many other objects don't seem affected by this however.

    I modified the value in "hardware_settings_config.xm" l found in" hardwaresettings" in the save location,

    from "<lod_quality lodBias="1.0"

    to    "<lod_quality lodBias="0.1"

    Seems the "High" value of 1.0 is off significantly. If this is the normal behaviour of the game, I'd recommend this be changed in game, or users can modify it at their leisure. Didn't realise a lower value meant a higher LOD draw distance. Looks MILES better with this change, and performance seems about the same

  • Actually, there is a setting in nvidia inspector which lets you adjust the LOD (it's related to anisotrpic filtering, you'll have to force it through the drivers). Range is from +3.0 to -3.0 (higher positive value makes the picture lose detail and blurry, higher negative makes it sharper). It really helps older games look better.

    It seems this game treats the negative value same as positive, so the higher the value the more you lose in detail. I set to -3.0 to see the difference and the car in front of me was a total abomination. So I entered your suggested value and the trees were much much better (at least the ones in foreground). I assume 0.0 is the best LOD value.

    That was a good catch OP! Thx for sharing...
