5.1 HF Doesn't Like PBR Airports

Recommended Posts

The performance improvement with 5.1 HF was great, except for airports utilizing PBR materials.  My frames dropped in half at all PBR airports - LVFR KMIA, KMSY, KBDL and ORBX KBUR.  Not sure what the issue is, but even KMIA and KBUR with the PBR materials disabled, and with or without EA, the frames still dropped.  All other airports are the same or better with 5.1.  Anyone else experiencing this?

Not seeing that, at least at Orbx BUR. With PBR on, no static aircraft, lite VNY, 2048 textures, and no EA, getting 36 FPS (NCP limiter set at 36) in the NGXu VC.. VRAM 6.1/7.1.

VRAM usage is just garbage now.  We are technically back to square one - how similar is this it FSX 32bit days.  I am not spending $$$ for Nvidia 3090 card at this moment during pandemic.

KMIA (non pbr) with 4096 textures with FSLabs crashed before the sim even loaded - out of Video Ram 

Anyway back to the post

I did boot up with FSlabs on KMIA Nonpbr with 1024 textures set - I am getting 34-35 fps in VC with UTLIve2+Orbx Global+openLC NA+Pilot's 2020 Mesh

Thanks for the input guys.  I was at about 40 fps at MIA, now about 20.  Roughly the same at BUR.  If you all aren't seeing a drastic loss like me then there must be something wrong on my end.  I'll keep trying to chase it down.

I think on my Simmaket account I have bot a PBR and non PBR version of KMIA from LatinVFR

Good morning together! Please do post at LM support. This is important as lots of 3th party are not updating due the changes which probably have to come at the lighting (and PBR).

I will test also!
