1. Memory Management & Texture Streaming
The most significant change is the rewrite of the D3D12 memory heap allocation. Previously (1.465.282), the game would cache weather textures indefinitely. Build 1.478.564 introduces a "cyclic texture purge" that activates every 15 minutes during free-roam.
- Result: VRAM usage is now capped at 6.5GB (down from a leaky 11GB in the previous build).
- Impact: Users with 8GB GPUs (RTX 3070, RX 6600 XT) report a 20% improvement in 4K stability.
Should You Install It?
Yes, unequivocally. Build 1.465.282 was a nightmare for stability. Build 1.478.564 makes Forza Horizon 4 feel as polished as it did during the Series 35 update.
If you are a modder: Be aware that the executable hash has changed. Most game mods (particularly reshade injectors and car model swaps) written for 1.465.282 will break upon updating to 1.478.564. You will need to wait for your mod framework to update the offset addresses.
Verdict: A Required, Unloved Update
| Aspect | Verdict | |--------|---------| | Is it safe to install? | Yes. Those who stay on 1.465.282 will eventually lose online features. | | Does it add anything new? | No. Zero new cars, events, or radio songs. | | Does it break mods? | Yes for most game mods (e.g., Custom Event Tools). | | Final judgment | A necessary backend hygiene patch. Install it for stability, not excitement. |

The keyword includes a cryptic "-E..." suffix. In Forza Horizon 4 error logging, this typically refers to Error 0x803f900A or E: 0x89245108. Result: VRAM usage is now capped at 6

Forza Horizon 4 Update 1.465.282 → 1.478.564: What Changed in the Final Live Release?
Just when many thought Forza Horizon 4 had entered permanent maintenance mode, Playground Games and Turn 10 surprised the community with a pair of incremental but meaningful updates. The jump from 1.465.282 to 1.478.564 (across PC, Xbox One, and Xbox Series X|S) isn’t a massive content drop, but it’s a crucial quality-of-life and stability patch that signals continued respect for the game’s active player base.
4. Performance Regressions (The Cost of Change)
Not everything improved. A subset of Nvidia RTX 30-series users reported:
- A 5-8 FPS drop in the Edinburgh city center.
- Stuttering when using the drone mode.
- Rare texture flickering on the 2018 Aston Martin Vantage.
This suggests that while security and server paths were updated, the graphical optimization for specific GPU architectures may have been unintentionally altered—a classic “fix one, break another” scenario.
