Significant FPS reductions observed during combat in Battlefield 4
Significant FPS reductions observed during combat in Battlefield 4
Hey! I just wanted to mention that I haven't been a fanboy, so I was just trying to play Battlefield. But every few minutes the game drops to around 10 frames per second. Usually I'm stuck at about 70 fps on Ultra with an R9 290. With a slight overclock of 3% and a boost in energy via the AMD driver's Overdrive settings, I get around 1330 MHz RAM. I also play on Mantle, which seems to handle the CPU better—usually I see a small jump of 5-6 fps when switching, then it drops back down to about 76 fps.
So why isn't everyone complaining? Some say the FX 8350 is terrible, but that's not entirely true. It might be due to some software or optimization issues on AMD. I checked my RAM usage—around 6.5 GB with Mantle and 6 GB without DirectX. My CPU stays at about 83% load in Mantle and 100% otherwise, but it drops to around 30% when the game slows. That could be the CPU, but why do I see those solid benchmarks with consistent good FPS using the FX 8350 and R9 290?!? My GPU temps are high—up to 88°C—but I use FRTC to cap it at 74 fps so I stay within my safe range (48-75 fps) to avoid tearing. The R9 290 runs at a whopping 4.1 GHz with a huge 0.1 GHz boost, which is impressive.
My CPU temps max out at 65°C with a Hyper-412 chip that's clocked at 4.1 GHz, giving a massive 0.1 GHz jump. I own an ASRock Extreme 3 R2.0, but it overheats easily if you push it beyond 130°C (about 90°C). The issue is FPS drops below 20 and then jumps back up to around 74. What's going on? Thanks in advance!
Mantle has often led to problems like this. Particularly with software meant for beta testing...we can only hope it performs well. I've experienced sudden drops in framerate in Battlefield 4, such as the one described, likely due to using settings that strained GPU memory. It seems RAM was running low and the stuttering occurred abruptly. D: "dip as deep" Awwwwww yeahhhh
oke with directx i get 2 GB of vram usage lets see about mantle
Played BF4 using DirectX and Mantle, which are essentially the same engine. I used a GPU with a high MHZ, stable frame times, normal FPS around 70, and about 2.05 GB VRAM usage. The card I own is 4 GB, and it worked similarly on both DirectX and Mantle. The first stage was DirectX, then the second was Mantle. CPU usage was around 7.6 GB out of 8.1 GB, and deep dips caused level switching. It seems everything is connected, but I’m still trying to figure out what’s causing the issue.
