SHIV crashing with AA enabled

cdrsubron7 · 06-30-12, 04:32 PM

A couple of suggestions. First, where do you have SHIV installed? It should not be installed in C:\Program Files (x86). Anywhere else on your C: drive should be fine. Second, have you tried lowering your AA to 4x and seeing what happens then.

I have it installed on my E: drive. C: is an SSD drive with limited space so I'm using it for Windows only.

Yes, I've tried lowering AA settings for 4x and 2x but still get the corruption.

Finally, when I purchased the new PC, I just copy/pasted the SHIV folder over to the new PC rather than deal with the evil that is StarForce on my DVD.

For those less initialed perhaps you could use words for what AA,AF,MSAA and Vsync are?

I assume that it is Anti Aircraft, Anti Flatulence, Multiple Sclerosis Association of America, and Vasectomy.

Its either overheating (more AA = more work for your GPU, and the temps outside are quite high lately) or there is something in driver control panel. Unfortunately I dont have ATI, so dont know its control panel.
But what does it mean: AA 8x, AF 16x, MSAA. 8xAA is antialiasing, MSAA is antialiasing too. Did you meant you selected 8x MSAA (instead of other type of AA?).

Do you have any problems while playing other games, or doeas it happen only with SH4?
Maybe try different driver version (some newer betas)?

There are 12.7 catalysts available, with performance improvements for 7900 series.

By the way (personal question

), do you have sun halo with 8xAA enabled?

Another edit: you can monitor temps, fps, gpu usage with msi afterburner.

Temps are steady at 61C. It's unseasonably cool here on the west coast.

Yes, I'm using 8xMSAA. If I select adaptive MSAA, then the ship and sub damage skins appear invisible. If I select Super Sampling, there's a significant performance hit for no increase in quality.

I've tried the latest beta drivers as well as the last two official releases but there's no difference in performance and the issue persists with all versions.

Yes, I'm having troubles with other games as well but they are all known issues that affect the 7970 card. It really does seem to be a bit if a lemon. I'm hoping it's just crappy drivers as its a new card with new architecture and not a systemic problem with the card itself.

The issue seems specific to anti aliasing as the game will run without it enabled. I've just never seen a situation where AA will work at the beginning of each sortie from port and then degrade over multiple play sessions until I dock again when the game resets and AA works again.

I assume your PSU is sufficient for this GPU (its a high end one).
It seem likely its a driver problem. Maybe try to run with vsync on and see if the AA bug is still there. How many fps you got (usually)?
Other thing would be to try some 3rd party tool, similar to nvidia inspector, and set some compatibility flags for AA (if there is such thing for AMD).

1050 watt PSU. Ive been testing various in game graphics settings such as SSAO, V sync, etc but no luck so far.
