Periscope FPS issue for the tech heads
 

My game seems to run fine at all times, the only time I have trouble is when raising or lowering the scope. Just as it breaks the water and your scope blurs to simulate water on the lense my FPS drops way off. It makes it difficult to move my scope in rough waters and it also forces me to raise my scope higher than I would like to. Is there anyway to turn that effect down or off? The only thing that I can think of is that i am running on 4x AA, but like I said everything else runs fine. Should I be running adaptive AA instead? I dont even know what the diff is. Anyone else have that problem?

P4 2.0g
768mb RAM
ATI X1300

mine did the same thing right before the mobo fried:o new kick butt machine now:p

That would not be good for me. I know its old but I like to squeeze all the life out of my systems. Im planning on getting a used P4 2.8ghz chip for this system before I upgrade to a new machine.

That should be the reason. The X1300 is a low-end card and it´s simply not able to handle 4xAA in some situations.

Try turning down the particle rendering...ingame menu->options->video options

Get a nvidia card. you will not be disappointed.

Reason was the card that I did have it was way too dark to see anything at night.

I had a ATI X700. I now have a Geforce 7600 GS OC w/ 512meg of ram.

I would love an Nvidia card but you get what you can afford at the time right? When I play morrowind oblivion there is an issue with ati cards and AA. There is a part of the game that will drop your fps to a crawl when you look at it. Im wondering if its another issue like that.

They are in general not better than ATI cards.

Oblivion has some clipping issues, there are places where the framerate drops no matter which card you have. How much it drops depends on how fast the card is. With your X1300 you shouldn´t use AA at all, it´s too slow for that.

@nipples:

I used to have the same problems with my X300 SE (slow edition). It's a comparable card, yet even slower than yours. I upgraded my drivers and now it runs the dipping the scope effect just as fast (read just as slow) as the rest...

try it!

Well I upgraded to the newest version of cat drivers and turned AA down to 2x. The periscore it tolerable at this point but now when I do an external view of the sub my fps drops like a rock. Now I know this isnt a hardware issue bc the game runs fine with the wxception of these two spots. Also my external view was smooth as silk before I upgraded the drivers. Isnt anyone else having these spoblems with an ati card?

I'm using a X1950 XTX with 512Mb of GDDR4, so I don't think I'm much use to you as a comparison, sorry.

Try this... uncheck the square boxes "Controlled by aplication" or "Aplication Preference" i am not sure how it is called in english.... in both, AA and AF, and let the AA and AF in 2x.

Uncheck Temporal Antialiasing.

Check performance round box.

Try and comment... :up:

Its going to take me a minute to get out of my current game and try that but I will give it a try and post back here in a few mins.

Hrrm well at first glance it seems to have fixed it. :up: thanks. Somwhere between the driver update, game restart, and changing the aa setting through catalyst instead of the toolbar shortcut the problem went away. In fact I could probably turn it back up to 4x AA now muahahahaha <---evil laugh
