Hi guys i was just wondering what settings i could change in games to make them run better
i have an fx-8350 processor but a gtx970 graphics card and open world games dont really run that well

i was wondering if some settings in games could lower the load on my cpu and make the game run better

- thank you in advance :D :D :D

For that you will have to look at an in-depth analysis of game settings for each of your games. Each developer programs their games differently and may use the GPU for some calculations and the CPU for others. Generally audio is done on the CPU. If you turn audio quality to max it may move to the GPU. Some texture decompressions are done on the CPU as well. Your best bet would be to ask around on the game forums or if you're lucky enough get in contact with the game's support team to better fine tune your system.

I've noticed and read about some games with lower settings applied will move GPU workloads to the CPU. Such things include audio and some post FX processing like fire. Heroes and Generals is an example of one such game. The only thing I can say is play around with the settings and if you can't make headway so some extensive research on how each of the settings for your games.

I think there may be a patch that affects the hardware scheduler, since the bulldozer 8 core is actually 4 modules with one floating point core shared with two integer cores. Basically it makes the cpu act more like a 4 core/8 thread cpu, for instance core 0 2 4 and 6 get greater priority and they can use the floating point cores 1:1 and then cpu 1 3 5 7 act like intel hyperthreading.

Maybe your bios can allow you to disable cores and turn off the odd cores for testing to see if it will help your situation.

anyone remember the integer cpu 486 sx and the math coprocessor floating point unit 486 dx chips? since then every cpu had floating point built in to each core, until bulldozer decided to share one math coprocessor for two integer cores.

sorry im not very technologically advanced, where would i find the spot in the bios to disable the cores, my bios is pretty simple because im on a gigabyte board lol

I know some about computers. Have built and repaired dozens, and more. I am not sure kraelic was speaking English. You are not alone.

I would start with Anti-aliasing and it's many incarnations(FXAA, TXAA, MSAA etc.). Move on to shadows. Finally you can reduce draw distance if that option is available in your game. Then it's trial and error with the settings. A broader stroke solution that would reduce the load on both the CPU and GPU is to reduce your resolution.

Everything holds true above. Anti-Aliasing and Shadow quality/texture size are going to be the biggest impacts to performance. Generally going from most demanding to least for Anti-Aliasing is Super Sampling-AA, Mutli-Sample-AA, Fast Approximate-AA and Morphological-AA, Temporal-AA, and finally Subpixel Morphological-AA. SMAA is going to be the least performance hitting AA and in some cases does better than FXAA and MLAA. Not all games support SMAA but it's open source and it's super easy to force a game to load a DirectX DLL that will enable SMAA (among other neat post FX processes).

For shadows you want whatever option is "sharpest". Ignore the AMD/Nvidia special named shadow blurring techniques and whatever generic shadow blurring the game supports. Sharp shadows will give more jagged edges but will be less performance hitting. Obviously going with a lower shadow texture resolution will be lower performance hitting as well.

Textures is probably the next performance hitting. Some video cards may have the VRAM to load high-res textures however the GPU may not be powerful enough to process everything in time. My GTX970 barely has enough ram for highest textures in GTA5 at 1440p but doesn't have enough 'oomph' to get 60fps+. You may notice the GTX 1060 comes in either 3gb model or 6gb. You can opt for a 6gb model and go with a high resolution monitor. But some games may be so demanding that you may need to either lower the texture quality or in worst case lower the resolution the game is rendered at.

I take what I said about Anti-Aliasing being the most performance hitting. Game resolution is. Unless you talk about SSAA which renders the game at X times the current resolution of the monitor. Going 4x SSAA on a 1920x1080 monitor is like rendering the game at 4k.

that not my problem though i have a good graphics card, i wanted settings that affected the cpu because my cpu is way worse than my gpu
