Anyone currently digging into the new EA Javelin update for Battlefield 6? It looks like the devs have finally pushed a change specifically designed to mess with DMA (Direct Memory Access) users by targeting the hardware communication layer.
The technical implementation is interesting—reports show the anti-cheat is essentially throttling PCI bridge speeds when it detects 'unused' or unauthorized bus activity. This forces extremely slow read speeds, effectively nuking the performance of your DMA setup. If your firmware isn't handling its PCI configuration space perfectly, Javelin identifies the anomaly and cuts the bandwidth to a crawl.
Observed Technical Impacts:
If you're working on a custom firmware solution, you'll need to look at how Javelin handles PCI-e lane negotiation and TLP (Transaction Layer Packet) timing. They aren't just looking for signatures anymore; they're attacking the physical throughput to render hardware cheats useless.
Anyone else seeing the slow read issue on their cards after the latest patch?

Observed Technical Impacts:
- Read latency has spiked significantly for users with standard DMA configurations.
- The anti-cheat appears to be forcing a lower bus speed state (such as L0s or L1 power states) on the PCI-e lane occupied by the card.
- DMA-based visuals and logic are lagging or completely losing sync due to the throttled throughput.
