2K11 go slow when settings is maxed

When I turn on the Vsync and put Anti-Aliasing in 8x my fps drops to 35-40fps..
But when turned off my fps is 87-91 all settings high except the vsync and anti-aliasing...

This are the specs of my PC:

OS: Windows XP Pro
Resolution: 1280x1024
Processor: AMD Athlon(tm) II X4 635 Processor, MMX, 3Dnow (4CPUs), ~2.8GHz
Memory: 4096MB ram
Directx Version: Directx 9.0c
Video Card: ATI Radeon HD 4600 Series DDR3 1GB

Why you need those things? They don't really change anything. Just maybe smoothens sharp edges and thats it, but I don't use it, because I like that sharpness.

Maybe because of the processor? That's a beast PC considering you're living here in the Philippines.

Your video card sucks, aa is most computational power demanding function.

Well kabayan, the 4600 isnt a good videocard for playing today's game at max, then you force high AA and vsync and so there is your problem.

I concur. Your videocard is a budget card. At that resolution, the game should look fine and run well at 4x AA.

To check if the CPU is the bottlneck, enable task manager before playing the game and monitor the performance tab CPU usage graph. Fire up the game and ALT+tab a few minutes into playing a game (or when it starts to stutter) and check CPU usage, if any core is maxed out then you have a CPU bottleneck

Another possible problem is vRAM limitation. At my settings 1920x1080, max in game settings, 32xAA , supersampling and 16xAF, the game uses up to 900mb vRAM (you can monitor vRAM usage using eVGA precision or MSI afterburner's OSD monitoring),If you are saying that your settings is maxed out and at 8xAA, then I believe your vRAM usage must be very high, and if vRAM usage exceeds your videocard's memory, stuttering will occur. AA can give a considerable performance hit and you might want to tone that down. I would suggest dropping it to 4xAA or even 2xAA and enable 16xAF instead. Personally, I find AF equally, if not more important in 2k11 vs AA. I can not distinguish the difference between 4xaa and 32xaa but I can notice the quality drop if I dont set the game at 16xAF

Another issue is with vsync.The problem with vsync is, aside from capping your max fps to your monitor's maximum refresh rate, it also caps your fps to certain fps levels/steppings that your computer can constantly output.The good thing here is, aside from eliminating screen tearing (which can occur when your fps is higher than your monitor's refresh rate), capping your fps to a constant fps level controls your fps from drastic dips and spikes. I remember playing 2k9 on my GTX 260 and vsync OFF was terrible as, although I would get up to 90fps on the settings I play, it would also dip to the 70s and 80s and that is when you feel that the gameplay is not smooth (when fps changes dramatically). Turning vsync ON capped my fps to a constant 60 and it feels smoother vs 90fps that dips by huge percentages. (stable good fps > higher but unstable fps)

Unfortunately, when your computer cannot output a constant fps level (ie 60fps), It will drop and cap the fps to a lower stepping your computer can constantly perform atand the difference between steppings can be quite drastic hence giving you much lower fps.

In the manual for the PC version of BioShock, it states that when VSync is enabled the framerate is 60, 30, 20, or 15 depending on what the system can render at a given time. I've noticed in some of the levels that this can provide for some very jumpy performance, particularly when a large amount of smoke effects are partially in view.

To help you play at the highest smooth settings possible, you can try to disable vsync and check which maximum graphical settings you can play that you computer can perform constantly at more than 60fps. THen you can enable vsync so your fps stepping will be at 60fps

PS: I noticed you have a 1Gb card, so the vRAM should not be an issue in your case

Does Nvidia Geforce 9800gt works in windows XP and directx 9..

Yes

Your specifications suck man. Better buy a new one.

which HD4600 card do you have? the HD4670 is about at par with the 9600GT so the 9800GT is a step-up but not by much. If you have extra budget, may I recommend you wait a while for the GTX 550ti? they say its supposed to be "cheap" but perform in the GTX 460 territory

or if budget is tight, get an HD5770 or a GTS 450

GTS450 for the win. Inno3d GTS450 1gb shouldn't be more than 5,500

From what I read, the GTS 450 is about equal to a GTX 260, and I do remember being able to crank up high AA and AF at 1920x1080 + vsync ON and still get solid 60fps with my GTX 260 (paired then with an e8400 clocked at 3.6Ghz)

hey guys.. I will buy a new video card geforce gtx 460.. but I don't know which is better Palit or Inno3d..

They are about the same unless one card is factory OCed much higher than the other or one has a beefier and quieter cooler (more important for me). I would consider other factors too like warranty and bundle

ahhh I see in your sig that your using palit..

yeah, for reference GTX 570s (or any reference video card for that matter) the deciding factor would be stuff like warranty, bundle etc and of course the price since they are made by the same manufacturer anyway
