HTC,
I ran Sys Mon in the background last night with no changes to the texture size. You are correct, my available system physical memory goes right to zero with AHII Patch 4, then may increase to at most 10-20 MBs, but gets drawn down to zero constantly.
For whatever reason, the stutters weren't as bad as the previous evenings. My uninformed guess is that the old island map last night has fewer and less complicated textures than Mindanao? Does that make sense?
Towards the end of the evening I switched to 256 textures and did very limited testing. It worked fine.
Today I just logged on for about 30 minutes on Baltic map. I noticed from a fresh boot that in the tower I showed only 19.8 MBs of Video memory used. That's the lowest I've ever seen in AHII. System was still set to 256, no stutters at all, even starting first thing at a base under heavy attack with a furball right there. Video memory used climbed to about 32 MBs before I logged. I wasn't running SYS Mon, but I will tonight to see if I am constantly out of system physical memory with the 256 setting.
I couldn't tell any difference in the graphics between 256 and 512 textures. What does the change between 1024, 512, 256, make?
Flyingaround, I'm back at work so I can't tell you off hand where they are set exactly. I experiment a lot, but I think they are about mid way right now on all 3 sliders.
If you don't already, it helps a lot with FPS to hit Shift F3 when you are near the ground in a furball with smoke from buildings ect. The rest of the time I use Shift F1 or F2.
